Thanks. So what? Didn't we have this before? I sent a mail on May 21,
2010, with subject "kernel crash: scheduling while atomic". Eric Sandeen
said "I'm guessing you blew the stack".
So what should I do about it? I think I read about a patch that should
fix this. Seems Novell/openSUSE didn't backport it, so could someone
please guide me where to find it? And I guess I should report upstream,
right?
