[I had sent this mail to -current before, but no one replied. I'm trying again.] I havne't been able to get my machine to boot with pcm enabled since Feb 5. The last working kernel I have is from Jan 18. Here's the panic (I have a debug kernel lying around from this panic): Here's the panic: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x28 fault code = supervisor read, page not present isntruction pointer = 0x8:0xc01fe4e7 stack pointer = 0x10:0xce22dcd8 frame pointer = 0x10:0xce22dcdc 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 = 51 (ifconfig) interrupt mask = tty kernel: type 12 trap, code = 0 Stopped at csa_readio+0x17: movl 0x28(%eax), %edx db> trace csa_readio(c10b4904, 0) at csa_readio+0x17 csa_intr(c10b4900, 4003103a, 101, c117ed00, ce22dd88) at csa_intr+0x13 intr_mux(c0a65b40, 40020000, 40060010, c1170010, ce220010) at intr_mux+0x1d Xresume3() at Xresume3+0x2b --- interrupt, eip= 0xc018381f, esp=0xce22dd54, ebp =0xce22dd88 --- rtrequest(1, c117ed48, c117ed48, c117ed68, 101) at rtrequest+0x1b7 rtinit(c117ed00, 1, 1, c117ed00, 1) at rtinit+0xe7 in_ifinit(c10b9000, c117ed00, ce22decc, 0, cce8f440) at in_ifinit+0x189 in_control(cca1af00, 8040691a, ce22debc, c10b9000, cce8f440) at in_control+0x597 ifioctl soo_ioctl ioctl syscall (2f,2f,2f,0, bfbffdb0) at syscall+0x176 Xint0x80_syscall() Here's the config file that doesn't work (has pcm and xl0): =================================================================== # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # For more information on this file, please read the handbook section on # Kernel Configuration Files: # # http://www.freebsd.org/handbook/kernelconfig-config.html # # The handbook is also available locally in /usr/share/doc/handbook # if you've installed the doc distribution, otherwise always see the # FreeBSD World Wide Web server (http://www.FreeBSD.ORG/) for the # latest information. # # An exhaustive list of options and more detailed explanations of the # device lines is also present in the ./LINT configuration file.
