Bug#642409: linux-2.6: suspend from gnome shutdown fails when krb5/nfs4 user logged in
On 28/09/11 11:09, John Hughes wrote: I think you're right about the problems now being userspace. I feel that the hang after thaw problems I'm seeing are caused by krb5 - it seems to like to get itself into a situation where it has no krb5 ticket so it can't access my home directory which prevents the unlock window popping up so it can't get my password and ask for a new krb5 ticket. If I log on on another screen or serial terminal then the unlock dialogue pops up. I'm going to continue testing today but so far my feeling is that the patch works as advertised - nfs4 shares no longer prevent suspend from working. I think my hangs (system not restarting from freeze, especialy when first starting in the morning) are probably related to the situation described in Ubuntu bug https://bugs.launchpad.net/ubuntu/+bug/794112 and nothing to do with Jeff Layton's freezer patches. I've seen the error message described in the Ubuntu bug: Error: state manager encountered RPCSEC_GSS session expired against NFSv4 server. The bug report hints Error: state manager encountered RPCSEC_GSS session expired against NFSv4 server and I'm running a 3.1 kernel with a Debian squeeze userspace. I'll update the nfs utils and see whether that improves things. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Maybe... krb5 tickets are usually stored in /tmp, so it's probably not the lack of that. It is however likely that the GUI requires access to some files in your homedir, which might be problematic. Still though, it seems like as long as you have a valid ticket, the resume ought to work (assuming that rpc.gssd is back up and running). If I log on on another screen or serial terminal then the unlock dialogue pops up. That certainly sounds like you're needing to reestablish your credcache.

Bug#642409: linux-2.6: suspend from gnome shutdown fails when krb5/nfs4 user logged in
Well, after minor modifications (needed to include freezer.h in fs/nfs/inode.c and net/sunrpc/sched.c) I've installed Jeff Layton's patch from https://bugzilla.redhat.com/show_bug.cgi?id=717735 in my 3.1-rc7 kernel... ... and it seems to work. Or at least it works a lot better. I've suspended and restarted many times without problems. This is on the Dell Optiplex 390 (x86_64 processor). I will build a kernel and try on the Optiplex GX270 (x86 processor). -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

The kernel seems to be unable to freeze user tasks doing nfs ops. What are the oldest and newest kernels you've experienced this with (you can get kernel versions from the string starting with Debian in /proc/version, or from /var/log/dpkg.log)? Is this reproducible with a squeeze (2.6.32.y) kernel (or in other words, is it a regression)?
