Comment 1 Espen Stefansen 2007-12-11 21:04:09 UTC

I also get a bunch of these in /var/log/messages. Doesn't anybody have any idea 
what it means?

Comment 2 Espen Stefansen 2008-03-04 22:06:32 UTC

With the latest kernel updates, these messages have disappeared for me.

Comment 3 Dave Jones 2008-03-04 22:17:25 UTC

Neal, are you still seeing them ?

Comment 4 Neal Becker 2008-03-04 23:04:36 UTC

No, no more messages here.
