--8t9RHnE3ZwKMSgU+ Content-Type: text/plain; charset=big5 Content-Disposition: inline I upgrade my world to latest current yesterday. And it panic on my notebook during boot, around pci messages. I use GENERIC config for this testing. And I unset acpi_load, otherwise it will hang during boot. Here is the panic message. <cut> Pentium Pro MTRR support enabled npx0: <math processor> on motherboard npx0: INT 16 interface pcibios: BIOS version 2.10 Using $PIR table, 6 entries at 0xc00fe840 pcib0: <Intel 82443MX host to PCI bridge> at pcibus 0 on motherboard pci0: <PCI bus> on pcib0 Fatal trap 12: page fault while in kernel mode fault virtual address = 0xeb813 fault code = supervisor read, page not present instruction pointer = 0x8:0xc00eb714 stack pointer = 0x10:0xc06fda3c frame pointer = 0x10:0xc06fda3c 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 = 0 (swapper) kernel: type 12 trap, code=0 Stopped at 0xc00eb714: cmpb %cs:0x1(%esi),%bl db> tr kernbase(c0d31580,c04a499d,c06fdad4,50d,38) at 0xc00eb714 _end(cb9d08c4,c4f6ec8b,81067540,ffffe5,e67f2400) at 0xc06fdaa8 db> </cut> After binary search, I found the difference between panic or not is reversion 1.215 and 1.216 of sys/dev/pci/pci.c. Kernel panic all from 1.216 to 1.221 of pci.c. If you want to have more information, please let me know. --8t9RHnE3ZwKMSgU+ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (FreeBSD) iD8DBQE++arp4yBMH10rsRoRAqNdAJ9ejv8X5vHEQGJP0EAHs2C/w5s/bACeKGI4 ktURAi0uatKyjEyiHNladw8= =3zoe -----END PGP SIGNATURE----- --8t9RHnE3ZwKMSgU+--
