Description H.J. Lu 2007-01-24 16:44:46 EST
When I ran

# make -j4 xcheck PARALLELMFLAGS=-j4

on a dual core machine on 2007-01-24 glibc from CVS, kernel panicked:

BUG: spinlock lockup on CPU#0, ...

Comment 1 Chuck Ebbert 2007-01-25 13:49:55 EST
Which kernel was this?

And without exact addresses and offsets for the call trace it's
kind of hard to tell what happened.
Comment 2 H.J. Lu 2007-01-25 14:11:51 EST
It is 2.6.19-1.2895.fc6 i686 kernel. That machine doesn't have a serial
port and kernel panic doesn't happen very time. I will try to write
down the addresses next time.
Comment 3 H.J. Lu 2007-02-06 12:41:31 EST
It happened again with "make check" in glibc.

Comment 4 Chuck Ebbert 2007-02-09 13:19:32 EST
We are trying to recursively take hb->lock:
    taken at kernel/futex.c:futex_unlock_pi():1384

So the BUG_ON() message never even gets delivered.

Comment 5 Chuck Ebbert 2007-03-21 17:18:44 EDT
This should be fixed in kernel 2.6.20-1.2933.fc6, available in fedora-testing.

Can you test this?
