2.4.27 network related Oopses

[Andreas Steinmetz <ast@xxxxxxxx>]

[please CC me on replies as I'm not subscribed]

Below are two somewhat similar Oopses from two different systems with an 
identical kernel configuration (attached) captured with netconsole. The 
kernel is a 2.4.27 with some patches. The Oopses happen not often (once 
every 4 to 8 weeks on average). They do have in common that they happen 
when there is lots of disk I/O and network I/O.
