2.6.19-1.2895.fc6 kernel panic during glibc check
Last modified: 2008-05-06 14:09:55 EDT
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, ...
... dump_trace ...
... show_trace_log_lvl ...
... show_trace ...
... dump_stack ...
... _raw_spin_lock ...
... exit_pi_state_list ...
... do_exit ...
... die ...
... do_invalid_op ...
... error_code ...
... rt_mutex_next_owner ...
... do_futex ...
... sys_futex ...
... syscall_call ...
Which kernel was this?
And without exact addresses and offsets for the call trace it's
kind of hard to tell what happened.
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.
It happened again with "make check" in glibc.
BUG: spinlock lockup on CPU#0, ld-linux.so.2/7451, c0859f88 (Not tainted)
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.
BUG_ON(w->lock != lock);
new_owner = rt_mutex_next_owner(&pi_state->pi_mutex);
This should be fixed in kernel 2.6.20-1.2933.fc6, available in fedora-testing.
Can you test this?
