Binary package hint: linux-image-
I'm using 8.10 Kubuntu with all updates done on system.
System is a clean installed system with EXT4 formating and using 2.6.8-8 linux kernel.
System sometimes lock and freeze whole inputs even keyboard or mouse.
I have closed X and kdm and try to reprocedure same bug in console ( not konsole )
so i have killed X and kdm.
And try to compile qt-copy in one console and try to svn up on KDE and on other console
i tryto apt-get update to make system under CPU load. and after a while it happens again.
No Keyboard response no harddisc response total freeze.
I have waited a while after freeze and about 4 min later a text appeared on screen saying :
BUG: soft locking - CPU#0 stuck for 61s! [uic: 5356]
after waiting about 4 more minutes a newer but same text appeared unter this message :
BUG: soft locking - CPU#0 stuck for 61s! [uic: 5356]
BUG: soft locking - CPU#0 stuck for 61s! [uic: 5356]
There isn't any error records on /etc/log/messages releated on hardware while around freezing/locking times
And for information : Sometimes i have seen that i'm getting messages like disc is full but
I'm sure that it isn't. Because df shows me there are more than 7 Gb freespace. Not always getting this error.
if a file shows this error while i'm updating it i'm deleting it and downloading a bigger file system won't interrupts me
like saying disk is full. I think it is releated to Ext4.
But i'm not sure these 2 bugs releated or not.
Thanks

I have exactly the same problem with 2.6.28-8.26. The problem started to appear only recently (2-4 days ago). The problem manifests only when deleting files - it never triggers when adding files. The problem occurs regardless of X running. Interesting is that the problem occurs on 32bit kernel only - 64bit 2.6.28-8.26 does not seem to be affected.
