I just got a couple of oopses in 2.0.8 while doing some tcpdumps (with
ftp.funet.fi/pub/Linux/PEOPLE/Linus/net-source/tools/tcpdump-3.0.4-1).
This all happened with a pentium that I'v used for about a year
without anything like this, the pentium is a 75MHz cpu with 32Mb
memory (The pentium memcpy-patch is in use and has been in use for
months on this computer). I managed to get about 5 short tcpdumps
(5-10s) and then I started a kernel compile and tried to use tcpdump
again (while compiling), then I got an oops from the kernel, I tried
again and the same thing happend, I waited for the kernel compile to
finish and tried again, same thing. The computer is still up and
running, everything seems to work fine exept tcpdump. If anybody wants
more info, just ask...
Here's what I got.
