Hi!
I have found a few days ago strange messages in /var/log/messages
More than 10 times there was do_IRQ: stack overflow: (nimber).... followed
with code. If need I can send all this data. I have run
ksymoops with only first 3 cases. Here is the first, the second and
the third are in attachment.
After that oopses my system continued to work.

uname uname -a

Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
I have applies ebtables_brnf patch (http://bridge.sf.net) and a
small add to it. The problem occur a few days later I have installed a
new hdd.


My system works as a bridge.
Processor AMDK7-900

NIC Compex RE100TX(rtl8139 chipset)


If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
