Hi all,

This looks like a lockdep problem.
2.6.21-rc6
+ hrtimers_debug.patch (from Ingo)
- skge_wol_support (commit a504e64ab42bcc27074ea37405d06833ed6e0820) dropped due to
swsusp problems

BTW. I noticed some strange fio (1.15) behavior
Starting 16 processes
file:io_u.c:65, assert idx < f->num_maps failed[ 1605/ 36442 kb/s] [eta 00m:32s]

file:io_u.c:65, assert idx < f->num_maps failed[ 10452/ 0 kb/s] [eta 00m:23s]
