Be sure to reboot then run reiserfsck.
OHCI lacks suspend/resume support. Turn it off. ... ... but it should
not do this kind of corruption. Can you reproduce this without OHCI?
Can you try -test3?

When I tested -test3 a few week ago, I hadn't got this problem.

Okay, try this patch, then invoke swsusp with this:
root@bug:~# cat swsusp.c
void
main(void)
{
reboot(0xD000FCE2, 0);
}
root@bug:~#
If it helps, it is patrick's swsusp changes, else it is patrick's
driver model changes or some driver bug.

Could someone that is familar with reiserfs comment as to what exactly is
happening?
Mathieu, did you notice this with any of the earlier -test4-mm6 kernels,
or just -mm6?
Thanks,

Hi,
I haven't tested previous -test4-mm patches before this one, so I
couldn't tell you :(
In addition, as I said to Pavel in private mail, this laptop is not
mine, and I won't be able to execute more tests on it.

Ah. I'm sorry to hear that. Thanks for testing anyway.
If someone has tested suspend-to-disk while using reiserfs, I would be
very interested to hear if they have or have not had success.. (For the
record, I use ext3 and have not seen any comparable problems).
Thanks,
Pat
