I thought we got rid of this kind of panics finally? Apparently not: uriah # dmesg -M vmcore.30 -N kernel.30 |tail bppp0: phase authenticate bppp0: phase network bppp0: phase terminate bppp0: phase dead panic: lockmgr: locking against myself syncing disks... panic: lockmgr: locking against myself dumping to dev 409, offset 134464 dump 32 31 30 29 28 27 26 25 24 23 22 21 20 19 ... Coredump still available. Can i do something with it to help analyzing the problem? The crash happened towards the end of a `make release', apparently while writing to a vn device: panic: lockmgr: locking against myself #0 0xf01215c7 in boot () (kgdb) bt #0 0xf01215c7 in boot () #1 0xf01218a3 in panic () #2 0xf011ce40 in lockmgr () #3 0xf01c0733 in ufs_lock () #4 0xf0146847 in vn_lock () #5 0xf010b822 in vnstrategy () #6 0xf014f49a in spec_strategy () #7 0xf013a8b2 in bwrite () #8 0xf013a8fe in vn_bwrite () #9 0xf013b2a3 in vfs_bio_awrite () #10 0xf01baade in ffs_fsync () #11 0xf01b954f in ffs_sync () #12 0xf0142503 in sync () #13 0xf0121491 in boot () #14 0xf01218a3 in panic () #15 0xf011ce40 in lockmgr () #16 0xf01c0733 in ufs_lock () #17 0xf0146847 in vn_lock () #18 0xf010b822 in vnstrategy () #19 0xf014f49a in spec_strategy () #20 0xf013a8b2 in bwrite () #21 0xf013a8fe in vn_bwrite () #22 0xf013b2a3 in vfs_bio_awrite () #23 0xf013b548 in getnewbuf () #24 0xf013bbac in getblk () #25 0xf013a5f1 in bread () #26 0xf01b6e75 in ffs_balloc () #27 0xf01ba229 in ffs_write () #28 0xf010b888 in vnstrategy () #29 0xf014f49a in spec_strategy () #30 0xf01c0846 in ufs_strategy () #31 0xf013a8b2 in bwrite () #32 0xf013a8fe in vn_bwrite () #33 0xf013aa7c in bawrite () #34 0xf01ba41c in ffs_write () #35 0xf0146439 in vn_write () #36 0xf0129a5d in write () #37 0xf01df533 in syscall () -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
