[Bridge] recent crashes? Linux kernel 2.6.18-1.2239.fc5 (Linux Fedora Core 5)

Recently, possibly since the most recent one or two kernel upgrades in
Linux Fedora Core 5, my system has been crashing with a kernel panic.
The panic prevents anything useful from being written to any log files,
but on the crash trace left on the screen each time I always see
something which looks like it is in the bridge code.

 

This system is based on Linux Fedora Core 5, and currently has the
following showing up with "kernel" in the name in the output of "rpm -q
-a":

kernel-2.6.18-1.2200.fc5

kernel-2.6.18-1.2239.fc5

I'm a bit concerned about the fact that more than one single kernel
instance appears in this output! Not sure that I've ever seen that
before... "dmesg -a" shows that it is the .2239 version of the kernel
which is booting.

 

The system has 576MB of RAM (dmesg -a shows 575MB, I think it shares 1MB
with an on-board video module; this thing never runs in graphics mode
anyway). It has a Celeron 766MHz CPU. 

 

I've pasted the output of "dmesg -a" at the bottom of this email, in
case it provides any useful diagnostic information.

 

I know this is very little information. I'm hoping that what is
happening here is an incompatibility between a recent Fedora Core 5
kernel upgrade and the bridge code, and that others have seen it, and
someone knows a fix / workaround; or that there is some kind of attack
going on which is randomly hitting my system and triggering the panic,
and, again someone has seen it and has a fix / workaround.

 

Thanks very much!
