I've had two issues with this kernel and am curious who else is having similar problems. ::Issue #1:: Although it seems benign/recoverable, for the first reboot after installing this kernel I get an error in the logs that the system can't load what's listed in modules.dep because it can't find the file modules.dep--even though the file exists. A second reboot and then the system has no problem finding the file. ::Issue #2:: This one is a show stopper: With the -10 kernel we get frequent hard lockups, about once every hour or two. Doing a ctrl-alt-bkspc fails to restart the X server; the keyboard and mouse become frozen/non-responsive, and the only recovery is via the power button. We can see this coming when we go to launch an app, we get the bouncing mouse cursor, and then the app fails to launch and the mouse cursor returns to normal. At that point, the next app we launch will lock the system up. There's nothing in the logs. We went back to the -5 kernel for a while, waiting to make sure the revised -10 packages hit all the mirrors. Then, late last week we reinstalled the -10 kernel from the ftp.gwdg.de mirror. And we still have the same problems. So, for the moment we've gone back to the -5 kernel, and the system has had no lockups for the past two days. Anyone else seeing either of these?

And we still have the same problems. I am using the -10 kernel with no problems. WRT: Issue #2. I have seen cases where either KDE or X lock up (not on the 2.6 kernel, but on earlier 2.4 kernels. In most cases I was able to log into the locked up system via the network, and simply kill the GUI. (init 3 is generally the best way to do it). The problem is that the GUI owns the keyboard and the mouse, so while your GUI locks up, the system remains available. I'm wondering if the issue you see in #1 may be related to #2. Might you have some kernel modules that are not matched to the -10 kernel. Or, it may not be a kernel issue at all, although the logical assumption is that the system is locked up.
One way to test this is to try to come in the back door via the network. If
you get in, take a look at the top CPU hogs first. I found that KMail using
IMAP tended to get stuck in a loop.

I am still running -5, but I had a lockup like you describe on one of my machines over the weekend. I had to cycle power to wake it up. That particular machine does not even have X running, so it was pure text mode. That machine gets booted a lot, because I am moving disk drives in and out of it regularly, but I don't remember any other time I was forced to reboot it. Also, it is not networked, so I don't know if the NIC was still functional or not. Greg -- Greg Freemyer
Hi, I have the same problem in my box (Issue #2). I improved the stability disabling the NVDIA driver (with 3D support) and my system only failed one time after this change. It seems that the problems appeared after the 2.6.8-24-10 kernel update. ¿There are new -10 packages that solve the problem?

Problems appeared again. I'm starting to think that is a problem with hardware. I'm testing with some hardware config variations...

I used memtest86 to check the computer memory and I have found that one of my DIMM modules is buggy. In a few days I will confirm if this is the problem source (and not the kernel update).

I just ran "memtest" on the machine I had experienced a lock-up on and it too failed. Greg

In my "memtest" run I experienced the same two things: look-up and fails. I removed the supect DIMM and now I am testing my computer with this new config. Today my computer worked fine, but it is eary to get a conclusion about this problem. This night I will run a full "memtest" with the suspect DIMM removed because yesterday I only had time to do a partial test. I will post my results soon...

You *may_indeed* have a memory problem ...but this box came back from being checked out w/a clean bill of health ...and the same kernel caused a major melt-down. FWIW, I have sent SuSE a whopping bunch of data on all kernel-2.6.xx-xx releases pertaining to problems. Hope it'll get fixed!! -- ..."Yogi" CH Namasté Yoga Studio
