2.6.7-bk5 scheduling while atomic

2.6.7-bk5 scheduling while atomic

[Klaus Dittrich]

System smp (2 x XEON, I7505) preemptive 

With kernel-2.6.7-bk5 I get a lot of 
"kernel: bad: scheduling while atomic!" messages 
during startup.

2.6.7 runs fine using the basically the same configuration.

Did anybody else see this ? 

Here is an excerpt of /var/log/messages  ..

Yes, same here.
kernel-2.6.7-bk5
SMP (2 x Pentium II)

2.6.7 runs fine.

The specific messages are different in my log
but the structure is the same: floods of
scheduling while atomic messages.

yes, "me too". but i was not able to get the messages flushed to the
disk. this is 2.6.7-BK kernel from 2004-06-21 (around 4p.m., GMT+1).

it happens upon mounting of nfs shares from a linux 2.6 kernel-nfs
server; the console is flooded with messages like yours and also i don't
have them at hand, i'd say they are the same.
