We've got another mystery panic in 7.2-PRE. Upgrading is not an option; however, if this is familiar to anyone, backporting a patch would be. The stack trace is: db_trace_self_wrapper() at 0xffffffff8019120a = db_trace_self_wrapper+0x2a^M panic() at 0xffffffff80308797 = panic+0x187^M devfs_populate_loop() at 0xffffffff802a45c8 = devfs_populate_loop+0x548^M devfs_populate() at 0xffffffff802a46ab = devfs_populate+0x3b^M devfs_lookup() at 0xffffffff802a7824 = devfs_lookup+0x264^M VOP_LOO[24165][irq261: plx0] DEBUG (hasc_sv_rcv_cb): rcvd hrtbt ts 24051, 7/9, rc 0^M KUP_APV() at 0xffffffff804d5995 = VOP_LOOKUP_APV+0x95^M lookup() at 0xffffffff80384a3e = lookup+0x4ce^M namei() at 0xffffffff80385768 = namei+0x2c8^M vn_open_cred() at 0xffffffff8039b283 = vn_open_cred+0x1b3^M kern_open() at 0xffffffff8039a4a0 = kern_open+0x110^M syscall() at 0xffffffff804b0e3c = syscall+0x1ec^M Xfast_syscall() at 0xffffffff80494ecb = Xfast_syscall+0xab^M --- syscall (5, FreeBSD ELF64, open), rip = 0x800e022fc, rsp = 0x7fffffbfa128, rbp = 0x801002240 ---^M KDB: enter: panic^M -- Charles R.
