Oops in 2.4.12

[Robbert Kouprie]

Hi all,

Today I found this oops in my logs. The oops originated from a smbd
process (Samba 2.0.9 stable). Earlier kernels (except for pre-kernels)
never gave me problems. 2.4.10 was the previous used kernel on the
system and did not give any oops for about the 2 weeks it ran on this
system. The system did not crash after this oops. Can someone make more
out of than I can, or point me to a possible bug(fix) that is related?
