Hello All , Here we go again . Again attempting to do bonnie++ testing
on a small array .
Kernel 2.6.22.1
Patches involved ,
IOP1 , 2.6.22.1-iop1 for improved sequential write performance
(stripe-queue) , Dan Williams <dan.j.williams@xxxxxxxxx>
Hello James,
Thanks for the report.
I tried to reproduce this on my system, no luck.
Possibly because there is significant hardware differances ?
See 'lspci -v' below .sig .
However it looks
like their is a potential race between 'handle_queue' and
'add_queue_bio'. The attached patch moves these critical sections
under spin_lock(&sq->lock), and adds some debugging output if this BUG
triggers. It also includes a fix for retry_aligned_read which is
unrelated to this debug.

Applied your patch . The same 'kernel BUG at drivers/md/raid5.c:3689!'
messages appear (see attached) . The system is still responsive with your
patch , the kernel crashed last time . Tho the bonnie++ run is stuck in 'D' .
And doing a '> /md3/asdf' stays hung even after passing the parent process a
'kill -9' .
Any further info You can think of I can/should , I will try to acquire
. But I'll have to repeat these steps to attempt to get the same results .
I'll be shutting the system down after sending this off .
Fyi , the previous 'BUG" without your patch was quite repeatable .
I might have time over the next couple of weeks to be able to see if it
is as repatable as the last one .
