The second try with the patched 2.6.36-rc6 got stuck again.

I just tested vanilla 2.6.35, userspace and the testcase as with the
2.6.36-rc6 kernel.
Behavior was the same as with the first try of the patched 2.6.36-rc6:
The testcase started to build up CPU load and memory pressure, then
the mouse got stuck. After ~1 min the system recovered and KDE became
usable again. (Compile just finish OK)

Yes, if a swapstorm occurs, I can live with a (short) "lockup". For
example compiling openoffice on tmpfs is a case where I have seen
similar short periods of the mouse getting stuck. But with 2.6.36-rc5
it was the first time that the system did not seem to recover, so I
think it should count as a regression compared to 2.6.35.

As the second try with the patched 2.6.36-rc6 got stuck again, could
it be that your patch is incomplete?
>From drivers/md/dm-crypt.c:
cc->io_queue = create_singlethread_workqueue("kcryptd_io");
cc->crypt_queue = create_singlethread_workqueue("kcryptd");

Do these workqueues also need WQ_MEM_RECLAIM?

I have attached the SysRq-M output from the patched -rc6. The symptoms
were the same as with the unpatched kernel. The system got stuck, the
hung_task_timeout triggered for a numer of programs in sync_page() or
do_lookup() and one kworker/1:1:496 was probable the nail in the
coffin.

Do you want me to do more tests with 2.6.35 or the patched .36-rc6? Or
any other patch I should try?
