Full dmesg output can be mailed, if necessary. >Description: Today I've added the emu10k1 driver to my kernel after cvsup'ing the sys collection (as described in freebsd-questions). Before this, the machine was running perfectly in SMP mode, with linux emulation enabled, and playing music over the (also installed) AWE64. But now i wanted to have two sound cards supported. After booting the new kernel in single-user mode, i could use the SB Live! to output sound, trying a "mixer" on the AWE64 device gave something like "device busy" and did nothing. mpg123 worked well with the Live! device, while the AWE64 remained silent, but the machine stayed alive, so I went multi-user. When rc.i386 turned on the linux emulation, the machine went to the kernel debugger and printed the following messages (which don't really clue me up): Fatal trap 12: page fault while in kernel mode mp_lock = 01000002; cpuid = 1; lapic.id = 00000000 fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc0e85dbb stack pointer = 0x10:0xcd23cf0c frame pointer = 0x10:0xcd23cf28 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enable, resume, IOPL=0 current process = 145 (ldconfig) interrupt mask = none <- SMP:XXX kernel: type 12 trap, code=0 Stopped at linux_open+0x23 subl 0(%edx),%eax >How-To-Repeat: Only tried this on my machine, as described, I don't know any other computer with this hardware configuration and FreeBSD 4 >Fix: Sorry, no clue. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
