[Bug 553666] [NEW] BUG: soft lockup - CPU

Thu Apr 1 22:49:08 UTC 2010

Public bug reported:

Binary package hint: linux-image-2.6.32-18-generic-pae

Everytime the system is put to sleep, then awakened several messages like these below show up in the kernel log:
The Pid/Program is not always Xorg - seems to just be whatever programs are active.  It does eventually stop.  System stability does not seem to be affected.  This did not happen in Karmic, only Lucid with all current updates.
