"BUG: unable to handle kernel paging request at 0011fa87" message in dmesg when moving file between RAID-0 (reiser formated on /dev/hda1 /dev/hdc1) and reiser partition /dev/hda2. System irresponsibe after that. Reproducible: Sometimes Steps to Reproduce: 1.Setup system as showed 2.copy/move 36GB in several files from RAID to partition 3.you get it (3 times reproduced) Actual Results: System irresponsibe, reboot needed. Expected Results: files moved without errors Changing partition from reiser to ext3 removes BUG so no idea where BUG is it; memory management or reiser filesystem ¿? /var/log/messages output: Mar 29

Please test with later kernels. Upstream and Gentoo no longer will be releasing any 2.6.29 kernel.
(In reply to comment #1) > Please test with later kernels. Upstream and Gentoo no longer will be releasing > any 2.6.29 kernel. I had this for a file on my 2.6.31-gentoo-r6 kernel. I removed it already, however, and am not interested in trying to aggravate the problem by moving loads of data around and I haven't seen this problem pop up since I removed the file. $ uname -a Linux ohnopublishing.net 2.6.31-gentoo-r6athlon64x2_2009.05.31 #1 SMP Thu Dec 31 18:42:07 EST 2009 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ AuthenticAMD GNU/Linux
ok, sounds fine,
