If I remove my /etc/devfs.rules file, the panic =20 does not happen. Can anyone point out what is wrong with my =20 devfs.rules what the new path matching logic doesn't like? $ cat /etc/devfs.rules.old [localrules=3D10] add path "da*" mode 0660 group operator add path "usb/1.2.0" mode 0660 group uucp add path "usb/4.3.0" mode 0660 group operator The panic, as transcribed from screen: Fatal trap 12: page fault while in kernel mode fault virtual address =3D 0x0 fault code =3D supervisor read, page not present instruction pointer =3D 0x20:0xc06dde21 stack pointer =3D 0x28:0xe8690a48 frame pointer =3D 0x28:0xe8690a80 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, def32 1, gran 1 processor eflags =3D interrupt enabled, resume, iopl =3D 0 current process =3D 577 (ln) trap number =3D 12 panic: page fault KDB: stack backtrace: #0 0xc0670ece at kdb_backtrace+0x50 #1 0xc06449fa at panic+0x132 #2 0xc07eb1d2 at trap_fatal+0x21e #3 0xc07eb4e0 at trap_pfault+0x1c2 #4 0xc07ec251 at trap+0x3c1 #5 0xc07d95fc at calltrap+0x6 #6 0xc05c7001 at devfs_rule_run+0x13d #7 0xc05c70c3 at devfs_ruleset_applyde+0x25 #8 0xc05c71b3 at devfs_rules_apply+0x73 #9 0xc05cad51 at devfs_symlink+0x124 #10 0xc080d084 at VOP_SYMLINK_APV+0x4a #11 0xc06d2985 at kern_symlinkat+0x38b #12 0xc06d29da at kern_symlink+0x2e #13 0xc06d2a05 at symlink+0x29 #14 0xc07eb7c7 at syscall+0x1a1 #15 0xc07d9661 at Xint0x80_syscall+0x21 Thanks in advance! --=20 Toomas Aas Tartu linnakantselei arvutiv=F5rgu peaspetsialist tel 736 1274 mob 513 6493
