Subject: detected stall on CPU 1 (t=0 jiffies) - huh?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Last night my working machine produced the attached kernel messages.
The machine was completely idle at the time. If I understand
Documentation/RCU/stallwarn.txt and kernel/linux/kernel/rcutree.c
correctly, "t=0 jiffies" is somewhat nonsensical.

uname -a says:
Linux xenon 3.2.2-capigig #1 SMP PREEMPT Sat Jan 28 01:59:16 CET 2012
x86_64 x86_64 x86_64 GNU/Linux

The processor is a dual core Intel Pentium D. The taint is from the
VirtualBox modules, in case it matters.

Should I just ignore that message?
