Hi everybody
I'd a thread with Mark Hahn and Denis Vlasenko about cpqarray and SMP
problems with 2.4.14. but they told me that it's better to go now on the
mailing list because the problem become harder.
I'll resume this and hope it will be usefull for everybody.
The machine:
Compaq Proliant DL 360
2 HD scsi 9,1 G
Raid 1
2 eepro 100
SMP (but 1 CPU)
The partitions:
/dev/ida/c0d0p1 swap
/dev/ida/c0d0p2 /
/dev/ida/c0d0p3 /tmp
/dev/ida/c0d0p4 /var
The problems:
1 When i want to edit a file: /var/log/mylogdir/mylogfile (140 Mb)
the server hangs whith this messages:
invalid operand

<0>Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing
2 If i want to copy /var/log/mylogdir/mylogfile
Kernel says:
invalid request on ida/c0d0 = (cmd=30 sect=837624 cnt=248 sg=1 ret=10)
When this arrived i didn't know about ksymoops but i find in Sysmap
only answers for "Call Trace":
c0105360 t default_idle
c0105000 T _stex
I think to that when the system want to swap it hangs to (writing on
another partition), and it was the same when he wants to rotate a file
which is to big for the "bug" .
I've to say that these didn't arrived when i did the same tests with
little files.
##############
When i tried to find a solution for this problem, i read the kernel
changelogs since the 2.4.13 and if find that the cpqarray was modified
for the 2.4.14, then i downgrad to the 2.4.13 and now everything work
fine.
Can you confirm that downgrading was the solution or explain if it's
another problem and which one.
Is the modification for cpqarray solving this problem (i don't want to
use it now it's only for my knowledge :-) ).
I'll thank you very much
Best regards
PS: excuse me for my bad english
