I was wrong - it's in vanilla tree
(http://www.stardust.webpages.pl/files/mm/2.6.18-rc6-mm2/mm-dmesg1).

cat hunt | head -n 3
origin.patch
BAD
libata-ignore-cfa-signature-while-sanity-checking-an-atapi-device.patch

I can reproduce this bug with all CONFIG_DEBUG_*=y.
(only
CONFIG_DEBUG_SYNCHRO_TEST=m
CONFIG_RCU_TORTURE_TEST=m
as modules)

I have checked memory
http://www.stardust.webpages.pl/files/crap/memtest.jpg and everything
seems to be fine.

Regards,
Michal
