Xorg.0.log
I also think that a memory or cpu-error can be ruled out as my windows on the same machine never crashes - at least not due to memory or cpu errors... ;) So overheating, etc. are most likely not a factor. I forgot to mention, that I encrypt swap and /home with cryptsetup-luks. Investigating further into that direction, I found http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/1942/match=freezes which may be related. I will try out the proposed workaround of renicing kjournald and tell, whether it works. Didn't work, system froze again. I just saw, that the OP in the dm-crypt list only had temporary freezes, mine are definitely not temporary... I pinpointed the problem to be with the encrypted partitions. After having switched back to unencrypted /home and swap, no freeze happened. After four days I tried encrypted swap again and the system froze on the next yum update (when it swapped a lot). So I am certain that the problem lies somewhere within the crypting-facility. Renicing kjournald - as stated in Comment #6 - did not help. I cannot tell when this phenomenon appeared for the first time but I do know, that there were kernels (back in FC5), where this problem did not occur! Please close this bug or mark it as duplicate (maybe https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=216371 ?). BTW, is anyone actually reading this report, except for me? Can you retest with the newest kernel? (There've been some dm-crypt changes recently that might have fixed it.) I tried encrypted swap with the latest kernel 2.6.18-1.2869_1.fc6.cubbi_suspend2
and it seems to work, I was at least not able to provocate a freeze, despite
sizing the laptop's memory down to 256 MB.
Just out of interest, which is supposed to be the relevant change in the kernel?
The only dm-crypt related entry I could find is in the changelog of 2.6.18.6:
commit 43e5eb5c8cd3194f747c0a82b9939bfc48f352c5

[PATCH] dm crypt: Fix data corruption with dm-crypt over RAID5
Well, IMHO this bug can be closed now. When I have some time, I will retest with
encrypted home.
Closing this bug - there were changes in dm-crypt in recent kernels (spec. in 2.6.19 - workqueue changes) and comment #10 says it works already... Please reopen this bug if you catch this problem again with new kernel, thanks. |
