Hmm, is there a missing rpm?

You don't utterly need the devel package. Only if you want to build packages against that kernel. In that case I built and up-ed also kernel-devel.

I installed this patch, and that stopped my external keyboard from working. it also uninstalled ndiswrapper and its kernel module.

Random mouse freezes that were fixed by kernel-desktop-2.6.34.2-0.1 from http://labs.suse.cz/jslaby/bug-625339/ are back with kernel-desktop-2.6.34.4-0.1.1.
I've reinstalled kernel-desktop-2.6.34.2-0.1 and the issue went away immediately.
The patch did it into 2.6.34.4. So we have yet another bug (a regression) introduced in between 2.6.34.2 and 2.6.34.4. How the freezes look like? Is it when I/O load is high? Is it when CPU load is high? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Basically mouse appears not to respond and screen content appear to freeze for 1-2 secs. I am not doing anything special - just browsing web pages and scrolling down using the mouse wheel. The notebook does not seem to be doing any CPU/HDD-intensive activity before the freeze (according to top and iotop before the freeze). After the freeze is over, iotop briefly shows a "jbd2/sdXX" generating some I/O, immediately followed by a "flush" task generating some I/O. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Well, symptoms of this issue were system freezes, not input device stuttering.

I previously circumvented the problem (in my case I would say it was "input device stuttering) by echo -1 > /sys/bus/usb/devices/1-4.2.2/power/autosuspend after installing above kernel, I did remove this from /etc/rc.d/boot.local, rebooted - and stuttering/freeze is gone!

this bug was not "initially about i915", since I was the one who filed it, and I don't have i915 graphics in my laptop...
Sorry I messed up. It was nvidia.
and the freezing is still there. last night everything worked fine, this morning the freezes are back.

@Flan Suse: I am stumped, but it appears that alleviates my problems with freezing too. I've been doing it for a couple of days and haven't had freezing. This makes absolutely no sense to me. Could it be psychosomatic? A placebo fix?
I am totally clueless why this works. It could be random chance, for all that I know. Maybe the freeze bug is somehow related to how the module is loaded with this kernel? Maybe when we unload the module manually and ask the system to "try again" it has a better chance of loading it "properly"? Maybe we're just getting better luck with out "coin toss"? I don't want to install a kernel of the day, for a few reasons. So I hope the fix comes to kernel 2.6.34.x eventually. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Freezes came back after upgrading to kernel 2.6.34.7-21, so I switched to the newest one from the update repo (2.6.34.7-0.3.1) which works well so far.
Unfortunately, on my system, upgrading to 2.6.34.7-0.3 makes no difference - still freezing like winter every so often ever since upgrading to 11.3. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Freezes came back after upgrading to kernel 2.6.34.7-21, so I switched to the newest one from the update repo (2.6.34.7-0.3.1) which works well so far.
Unfortunately, on my system, upgrading to 2.6.34.7-0.3 makes no difference - still freezing like winter every so often ever since upgrading to 11.3.
I loaded up 2.6.34.7-21 and applied the fix I mentioned in #74 above and the pauses remain gone for me on my ASUS with Nvida video chipset, OSS driver, KDE 4.5.1 so you might give it a try on your system as it might not be a kernel or video problem at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Does increasing the hardlock limit as described below help?

I was unaware of this thread, however, I came to the same conclusion as the posters, the LOCKS limits were/are too low. They seem to be set at @256 by default which is probably based upon a default memory of 512k or possibly 1G. However, I have 3G and many people have even more and I think that setting is probably low so when people start running KDE or other DE's that allow multiple screens and multi-tasking operations routinely and many of these tasks launch multiple threads you are going to run out of 'room' for processes and have to start locking (read waiting) for things to finish up before new things can launch or things that were sleeping can be reawakened and resumed. So, things like updating screens get delays because they are put on hold. Well, most machines have the memory and horsepower to handle more than 256 job/threads/memory requirements at once so don't need to be locked down so tightly IMO, so I raised the limit on my machine to 2048 Hardlimit and 512 softlimit both with @ which makes it an absolute limit in Kbytes rather than a % of memory "Limit the size of the memory that a single process may lock in physical memory (thus preventing it to be swapped out). Hard limit: Can not be increased by non-root. This value corresponds to ulimit -Hl Parameter is in percent of physical memory (unless you prefix it by @, in which case it means kilobytes), 0 means no adjustment." It has helped a lot and the problem is virtually gone unless my system is really overloaded, like when both cpu cores are at 100% and disk I/O is high and it is starting to use swap space and I'm running SVN refreshing the sources for KDE or some such. Then, I still notice some pauses, but when svn isn't running, I rarely notice any like I used to. Before, I would get 5-6 second delays every time KMail checked for mail on one of my various mail sources, which was every few minutes to one or another, but now, is very rare that I ever notice even a half second, if that. FWIW, my system is a homebrew Athelon dual core cpu w/32 bit 11.3 Suse running 2.6.35 and KDE 4.5.2 with 3G ram, 2TB in a raid5 array w/2 additional drives in a LVM and a couple of USB 1TB drives hooked on for diddling around and backups. This is tied into a wireless LAN talking to my big machine in the living room which has a 5TB raid5 and a 1TB raid5 and a SMC 8 port router tied into the other wireless and 2 other machines, one of which is my mail and www server and the other is my test machine that I do most of my beta testing on. I used to teach Linux in college, but since my stroke, I can't do that anymore so me and my cat mostly just enjoy puttering with what I *used* to be able to do efficiently and try and remember "how it used to be" and occasionally I still find something useful to do <grin>. Hopefully, something good will come from all of this. I do believe this 'pausing' issue is a scheduling problem because SuSE 10.3 -11.1 didn't seem to have this problem on the same machines with the same memory resources, but the new kernels and new DE's and applications have changed so radically and grown so complex that I don't think that all the "engineers" at Fort Bill Gates" could do any worse at screwing it up <grin>. Thankfully, with Linux, there is the labor of love of thousands working on it rather than the greed of a few hundred butchering it.

The bug is not in the driver, changing the driver doesn't help. Nothing really helps apart from changing the kernel. Changing the kernel to >=2.6.35 simply fixes the problem full stop.
I find this to be true as well. No matter which Nvidia driver I install, the problem of freezing / high CPU doesn't go away, unless I use a kernel later than 2.6.34. All is working well under 2.6.37 from the KOTD repo. This looks like an issue with kernel 2.6.34, and even on the latest available package in the main repos, it doesn't seem to have been patched with a fix. The only solution I found to work with the 2.6.34 kernel is the steps I wrote in comment #67 https://bugzilla.novell.com/show_bug.cgi?id=625339#c67 This is the "rolling the dice" workaround which might not always work. But once it does work, it seems to be okay until the next reboot. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As FYI - I find that with kernel 2.6.34.7 and nVidia driver 260.19.21 the issue also goes away (temporarily) when logging out and then back in (which resets X of course). It saves me that hassle of "telinit 3, do-the-hokey-pokey". -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
