I'm having an issue where after a fresh install of openSUSE 11.0 on an IBM T42p, the laptop just freezes 2mins after GDM bootup. 2GB machine, with no additional repos and packages selected during install. No compiz enabled (no time to enable as machine locks up). At this point, I can't Ctrl-Alt-bksp or drop into init 3 mode.

I've reinstalled several times all to no avail. The one thing I've noticed is that the wireless indicator on the laptop itself blinks like crazy while locked up, indicative of a kernel panic.

Any ideas?

I believe you can specify init level at boot time.

Also how about a base install and start simple as it may help you find what is causing the hangup.

change the options of reiserfs in /etc/fstab to noatime,noacl for example /dev/md0 / reiserfs acl,user_xattr 1 1 to /dev/md0 / reiserfs noatime,noacl 1 1 and you will be fine.

Not really - in this case, the original author did not want those extensions added, but the power of open source is that they could be added anyway. But the fact is, even though the code was open, nobody understood reiserfs as well as the folks who designed it.

The original author didn't want a lot of things, (including letting his wife live), but mostly because he had plans for reiserfs4. noatime has been there for a long time, but its only really useful in laptops, where it kept the disk spinning and interfered with power saving. On server class machines there is no reason to specify noatime. Noacl is the only thing Reiser didn't want because, as I say, that was planned for Reiserfs4, and he wanted to push v4. Notail is a performance enhancement and its presence or absence does not cause lockups. It used to cause problems for earlier versions of Lilo, but has never been an issue with Grub, and the Reiserfs developers confirmed it was not necessary since Lilo 21.6. notail has always been part of reiserfs. The boot loader was the only thing that had a problem with tail. Noacl and noxattr were the only things added by the "third party". (Specifically Jeff Mahoney at novell). These things are meant to be handled by the kernel, but the patch allowed them even when there was no kernel support. They may be the source of some problems when posix acl support is not built into to the kernel. Reiserfs3 is well understood. Suse has be maintaining it for years. -- ----------JSA--------- Sig line deleted for the humor impaired. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well, I'm not going to debate his sainthood here, but yes, he was focused on v4.

Sure there is. Think about it. with atime enabled: Every time you read from disk, you write to disk and update the atime field of all affected files. Every time you read from the disk cache, guess what? you write to disk and update the atime of all affected files. That's a performance hit, and a scalability bottleneck.

That feature has been in almost every nix filesystem for a long long time. Its your audit trail. It has its uses. (File aging among them). Yes its a minor performance hit. When I say minor, I mean the average user will not see a difference with it on or off. Try it and see. Its not as big a performance hit as you suggest because its just a directory write, which is already in memory and will be handled by the write-thru logic. Its not that big of a scalability issue either, because its done in the server hosting the file. Really, its been there since dirt. It only became desirable to turn it off with slow laptops operating on battery.

...

Notail is a performance enhancement and its presence or absence does not cause lockups.

Nobody that I know of has ever said that the notail option, or lack of it, caused lockups.

I thought thats what this thread was about. Did I misread the thread subject? -- ----------JSA--------- Sig line deleted for the humor impaired. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Can you provide more information on that? Since reiserfs is in the mainline kernel, not to mention that it's long been the default filesystem in suse linux enterprise, I'd be surprised if there was a known fs bug in the kernel that was not speedily fixed.

I'm running on a T42p here and not seeing this problem at all. Only problem I'm seeing is that suspend-to-disk doesn't work. Which vid driver are you using, and when you hit Ctrl-Alt-bksp, are you hitting it twice? Once won't kill X in 11.0.

FYI, just did a reinstall (trying to fix my hibernation problem) from the GM (as I'd updated from Beta3 using zypper dup), and ran into a couple of weird problems with the driver update for the kernel, but fglrx driver and compiz are now working again on my spare t42p. Playing around with compiz-manager, though, I was able to duplicate your issue with compiz blowing up, and a white screen of death (that was a new one for me) requiring a hard reset. Tomorrow I'd be happy to pull the machine out and plug it in, grab the xorg.conf file and share it if you like.
