After suspend and resume to/from S3 I see a lot of these messages in
the kernel log:
[11750.054031] WQ on CPU0, prefer CPU1
[11750.154023] WQ on CPU0, prefer CPU1
[11750.254022] WQ on CPU0, prefer CPU1
[11750.354022] WQ on CPU0, prefer CPU1
[11750.454018] WQ on CPU0, prefer CPU1

[11750.754039] WQ on CPU0, prefer CPU1
[11750.854020] WQ on CPU0, prefer CPU1
[11750.954024] WQ on CPU0, prefer CPU1

[11751.854033] WQ on CPU0, prefer CPU1
[11751.954029] WQ on CPU0, prefer CPU1
[and so on; seems not to stop]
This comes from drivers/oprofile/cpu_buffer.c
Bug or feature?
