I've found kernel, where it works. It's Vanilla v2.6.20. With Vanilla v2.6.22
it doesn't works at all. I've done some bisection with linux-2.6 git tree too.
git-bisect log is in attachment. Two skips in the middle - that's about when
kernel failed to build, and I've tried to skip some patches to successfully
build it. Finally, I've marked that bisection as bad one.
I hope, this will help.
So, here is the winner:
$ git bisect bad
df9e062ad994c4db683377b108c0dbed4690e4b0 is first bad commit
commit df9e062ad994c4db683377b108c0dbed4690e4b0

[SCSI] fusion - serialize target resets in mptsas.c
Fusion firmware requires target reset following hotplug removal event,
with purpose to flush target outstanding request in fw. Current
implementation
does the target resets from delayed work tasks, that in heavy load
conditions, take too long to be invoked, resulting in command time outs
This patch will issue target reset immediately from ISR context, and will
queue remaining target resets to be issued after the previous one completes.
The delayed work tasks are spawned during the target reset completion.
