Hello,
Just bought a CNet WLAN card, and it makes -CURRENT panic when inserted,
or if it is inserted while booting.
Userland installed from 20021101 snapshot.
Kernel from today: FreeBSD 5.0-CURRENT #0: Sat Nov 2 09:50:05 CET 2002
(second panic from me issuing panic from ddb)
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xd11fa000
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc01aa2d5
stack pointer = 0x10:0xcc00494c
frame pointer = 0x10:0xcc004b78
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 9 (cbb1)
panic: from debugger
Fatal trap 3: breakpoint instruction fault while in kernel mode
