Kernel Errors while Suspending to swap.. to worry about ?


Ive just recompiled my kernel to allow suspending to swap.

Code:
CONFIG_SOFTWARE_SUSPEND=y
this all works fine, nut after resuming, a dmesng shows many errors such as
Code:
bad: scheduling while atomic!

 [<c0105bc7>] do_notify_resume+0x37/0x3c
 [<c0105da6>] work_notifysig+0x13/0x15
are scheduling errors somthing to expect when suspending to disk ?
or is this somthing i should worry about ?

after a resume, everything works fine, and the system seems very stable.
