I've been having a heck of a time getting an ASUS P/I P55T2P4 motherboard working with my custom 2.2 kernels. I think it's related to the serial hardware somehow, but I need someone to decode this panic and confirm. I've included the boot info to help locate where it is. This is captured from a serial console (-h) output. The message appears just as the system would pop up the gettys: configuring syscons: keyrate. . Local package startup: Modula-3 sshd. starting local daemons:xdm pcnfsd msqld bb. Thu Feb 6 18:42:02 PST 1997 Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0x0 stack pointer = 0x10:0xefbffe2c frame pointer = 0x10:0xefbffe84 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 = 5 (sh) interrupt mask = net tty panic: page fault syncing disks... 22 21 19 10 6 done I can also get this panic (with the _same_ detail) if I exit X (I have a serial mouse) or when Kermit quits. I think it's having trouble closing the serial port. Disabling either port doesn't help. I can't try disabling both, then I can't run the apps that force the panic. Specs on this machine: ASUS P/I-P55T2P4 motherboard w/ P133 CPU, 32mb RAM FreeBSD: 2.2-anything Video: ATI Mach64 GX SCSI: NCR 53c815 Network: 3com 3c900 Audio: GUS PnP IDE/Serial/Parallel port board (parallel enabled only) The machine is otherwise perfectly stable. One odd note: If I run the 2.2-970206-GENERIC kernel, it works fine. X complains there's no shared memory or MIT-SHM extensions, but it works.
