FreeBSD: wifi-related kernel panics

October 24th, 2009 Nick No comments

On FreeBSD, I’ve had 13 occurrences of kernel panics under these circumstances as of the time I wrote this.

All occur when I run `sudo /etc/rc.d/netif restart`.
I am not sure what is entirely relevant, so I will list full system specs followed by the output of the kernel panic:

System specs:

  • Sony Vaio Desktop
  • Pentium 3 – 700 MHz
  • 370 MB of SDRAM

Drives:

  • one 60 GB IDE hard drive
  • one IDE CD drive

PCI cards

  • one linksys wireless card (unsure of exact model)
  • one firewire card (provides 2 firewire ports)
  • two NICs

The following is the output of the kernel panic, the last 2 lines appear when i hit the spacebar to abort the reboot:

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address    = 0xc2aee100

Automatic reboot in 15 seconds - press a key on the console to abort
