[Bug 567660] Re: Suspend and Hibernate cause ksoftirqd to use 100% of a cpu core on resume

[Shura]

It is definitely related to suspend. It does not happen all the time
though as my experiments show. Worst of all I am not able to suspend any
longer once the ksoftirqd is consuming 100%

Tasks: 181 total,   3 running, 178 sleeping,   0 stopped,   0 zombie
Cpu(s): 17.7%us,  4.6%sy,  0.0%ni, 67.1%id,  2.3%wa,  0.1%hi,  8.1%si,  0.0%st
Mem:   3645260k total,  1899984k used,  1745276k free,   149636k buffers
Swap:  3999992k total,        0k used,  3999992k free,  1019436k cached

Please let me know what kind of info I could provide.
