Hello,

I keep getting kernel panics on my system with output similar to this:

skb_over_panic: text:fffffffff80456cc4 len:2580 put:2580

(I copied this output by hand so there may be a typo or two)

Before this my kernel was 2.6.27.5 and I was still getting the same
panics.

I've traced down this problem some more.  It only happens when I send
more than a small amount of data from my OSX86 system to my linux
server.  I can download files from the linux server without any
problems, but if I begin to upload anything it will kernel panic the
system in 2 seconds or less.  I haven't had any problem with regular SSH
sessions, but if I send files using scp or SMB the linux kernel panics
almost immediately.

My OSX86 system is using an Asus Striker Extreme with onboard Marvell
88E1116 Gigabit Ethernet 10/100/1000Mbps and the driver is
nForcEthernetDriver.kext which uses forcedeth.

Christian <cjs@dhp.com> :

Can you reproduce the bug when nvidia's module is not loaded
after boot ?

Yes I booted without loading the nvidia module and have the same
problem.
