Thanks for the response! OK, I tried this again using a new vmcore and got something more useful: Unread portion of the kernel message buffer: sis0: discard frame w/o packet header Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xbfc04000 fault code = supervisor read, page not present instruction pointer = 0x20:0xc0a31f3a stack pointer = 0x28:0xe3fbbbd4 frame pointer = 0x28:0xe3fbbc14 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 = 34 (irq19: sis0) trap number = 12 panic: page fault cpuid = 0 Uptime: 2h37m48s Physical memory: 977 MB Dumping 164 MB: 149 133 117 101 85 69 53 37 21 5 #0 doadump () at pcpu.h:195 195 __asm __volatile("movl %%fs:0,%0" : "=r" (td)); The network card is being detected as an SiS 900: Jun 6 10:03:36 odin2008 kernel: sis0: <SiS 900 10/100BaseTX> port 0x2000-0x20ff mem 0x4a100000-0x4a100fff irq 19 at device 4.0 on pci0 Jun 6 10:03:36 odin2008 kernel: miibus0: <MII bus> on sis0 Jun 6 10:03:36 odin2008 kernel: sis0: Ethernet address: 00:1c:c0:2e:ee:ad Jun 6 10:03:36 odin2008 kernel: sis0: [ITHREAD] Has anyone had any good experiences with this chipset? I can find a few people with similar problems dating back to 2002, but none recently. It's on the supported hardware list. Any ideas as to a fix or workaround?
