Hi! Here this goes again. For 2.5.6-pre1 please look at: http://marc.theaimsgroup.com/?l=linux-raid&m=101484845527913&w=2 [1.] One line summary of the problem: Shutdown left (always) software raid array in unclean mode, next shutdown (during reconstructing) will cause kernel bug. [2.] Full description of the problem/report: With 2.5.6 (and 2.5.6-pre1 at least) shutdown procedure left raid array in unclean state. Next time when machine is going down (during reconstruction) there will be kernel bug in the raid1.c:656. This is completely reproductable. If you run shutdown after reconstruction has been finished, there is no problem. However raid array is again left in unclean mode. unmounting file systems kernel BUG at raid1.c:656 invalid operand: 0000 CPU: 0 EIP: 0010:[<c01dd40b>] Not tainted EFLAGS: 0010293 eax: cfe73c18 ebx: cfe73800 ecx: 00000001 edx: 00000003 esi: cfe16000 edi: cde73800 ebp: cfe17fe0 esp: cfe17f84 ds: 0018 es: 0018 ss: 0018 Process raidsyncd (pid: 10, threadinfo=cfe16000 task=c135d6e0) Stack: cfe73800 c136e500 c136e558 cfe17fe0 0000222a 0000176b 00001899 c01ddeba c01dded1 cfe73800 cfe16000 cfe1c160 cfe1c168 c01e2aea cfe73800 00000100 c137dea4 cfe1c160 cfe28000 00000000 c135d6e0 00000000 00000000 00000000 Call Trace: [<c01ddeba>][<c01dded1>][<c01e2aea>][<c0105614>] Code: 0f 0b 90 02 8f 93 26 c0 5b 5e 5f 5d 83 c4 10 c3 90 81 ec a0 [3.] Keywords: kernel bug, raid (raid1), md [4.] Kernel version (from /proc/version): Linux version 2.5.6 (root@eowyn.sillanpaa.jyu.fi) (gcc version 2.95.3 20010315 (release)) #3 Sun Mar 10 14:20:04 EET 2002 [5.] Output of Oops.. message ksymoops 0.7c on i586 2.5.6.
