kernel BUG

[Andres Gonzalez]

Hi,

When I run dmesg on my Fedora Core 7 box it has several entries like
this:

 =======================
BUG: at kernel/irq/manage.c:33 synchronize_irq()
 [<c1005e65>] show_trace_log_lvl+0x1a/0x2f
 [<c1006417>] show_trace+0x12/0x14
 [<c100649b>] dump_stack+0x16/0x18
 [<c104927e>] synchronize_irq+0x4c/0x65
 [<c10493cf>] disable_irq+0x27/0x2a

 [<c1027698>] run_timer_softirq+0x104/0x168
 [<c10247e8>] __do_softirq+0x80/0xf9
 [<c100707d>] do_softirq+0x77/0x103


I am assuming these are not good. This is a relatively new
install--perhaps only a month or two old. These BUG notices have only
recently started showing up.

Any clues as to what might be causing this?  and where I should start
to learn how to fix this?

Thanks,

-Andres
