Hi,
Ever since the updates to the new iwi firmware: sysutils/iwi-firmware3, I
have had intermittent crashes. I finally got around to compiling a kernel
with DIAGNOSTIC (and -g) and now I consitently get the following panic when
using ifconfig to configure iwi0 (which auto-loads the firmware):
panic: free: unaligned addr 0xc1fba010, size 262144, type devfirm, mask 4095
This is i386 current from 18 Jan 2007, basically GENERIC_LAPTOP.
Ideas anyone (besides submitting a PR)?
Thanks,
Sverre
