| |
Hello,
Total crash (Aieeee: Killing interrupt handlers...) on an compaq 6400R Dual PIII Xeon 500, 3GB Ram + 1G Swap, custom kernel (SMP, smartarray/eepro100 into kernel).
syslog says: Nov 9 13:05:54 eedn36ls kernel: Invalid request on ida/c0d0 = (cmd=30 sect=5490 904 cnt=112 sg=12 ret=10)
console: Invalid request ...(same as above) invalid operand: 0000 CPU: 1 EIP: 0010: [<c0123b3e>] EFLAGS: 00010046 eax: 0 ebx: edd98500 ecx: 1 edx: c1a80dc0 esi: 2 edi: c1a80dc0 ebp: 1 esp: c4039efc ds: 0018 es: 0018 ss: 0018
(...)
Process: swapper (PID: 0, stackpage=c4039000) ... .... Code: 0f 0b 8d 5a 24 8d 42 28 39 42 28 74 11 b9 01 00 00 00 ba 03
On the second crash, there was a slight change: No reporting about an invalid request on ida/c0d0 but:
CPU: 0 same EIP, EFLAGS
Process: mtest01 (PID: 683, stackpage=f7439000) ....
same Code: ...
It is reproduceable on 2.4.14 (first compile using 2.91.66 gcc, second 2.95.3 gcc) using mtest01 from the Linux Testing Project (ltp-20010801/ltctests/mem/mtest01). I also applied the newest microcodeupdate from Intel, stays the same. 2.2.19 is doing fine (with bigmempatch, of course).
I used params: ./mtest01 -w -c $[25*1024*1024] -p 60 and started 3 processes. This will allocate 60% of total system ram on each process in 25MB chunks and will write to it after allocating.
If more infos are required, I will try me best to write down the kernel-panic :) Please include me on CC.
