Just wondering.. I'm still getting this since early 1.1 (I think)..:

# > tcpdump
Unable to handle kernel NULL pointer dereference at virtual address c0000000
current->tss.cr3 = 00f24000, %cr3 = 00f24000
*pde = 00102027
*pte = 00000027
Oops: 0000
EIP:    0010:00000000

Process tcpdump (pid: 9993, process nr: 31, stackpage=0038d000)

Code: 01 00 00 00 df e9 00 f0 c3 e2 00 f0 df e9 00 f0 df e9 00 f0
Segmentation fault

# > tcpdump
tcpdump: listening on sl0

Stack values give me

00132998 t _dev_ifsioc
0019eb3c d _slip0_dev

I've sl0 and sl1, both were up. It happens the first time I'm running
tcpdump (vers. 3.0), after the first fault it works.
