BUG: scheduling while atomic - Linux 2.6.20-rc2-ga3d89517

[Fabio Comolli]

Hi list.
Just found this in syslog. It was during normal activity, about 6
minutes after resume-from-ram. I never saw this before.

Kernel .config is attached.

Please let me know if you need more info.

Best regards,
Fabio.
