Kirk and all, Recently a panic started appearing on mine and other's systems while under load. I have an SMP system with all UFS1+softupdates filesystems, 256MB of RAM, etc. I'm working to build a debug kernel and reproduce the panic so I can give a better stack trace, but until then this is what I have. Building a release triggers this pretty consistently, though it takes a couple of hours. Before my last kernel update, I was running from a kernel+world from mid-April with no problems. panic: bremfree: removing a buffer not on a queue panic messages: --- panic: ffs_blkfree: freeing free block cpuid = 1; lapic.id = 01000000 boot() called on cpu#1 syncing disks, buffers remaining... panic: bremfree: removing a buffer not on a queue cpuid = 1; lapic.id = 01000000 boot() called on cpu#1 Uptime: 5h52m18s Dumping 255 MB 16 32 48 64 80 96 112 128 144 160 176 192 208 224 240 --- #0 0xc01f4edb in doadump () (kgdb) bt #0 0xc01f4edb in doadump () #1 0xc01f5438 in boot () #2 0xc01f579f in panic () #3 0xc0234270 in bremfreel () #4 0xc02341a5 in bremfree () #5 0xc023d598 in vop_stdfsync () #6 0xc01bfb90 in spec_fsync () #7 0xc01bf228 in spec_vnoperate () #8 0xc02bda5d in ffs_sync () #9 0xc02490bb in sync () #10 0xc01f5041 in boot () #11 0xc01f579f in panic () #12 0xc02a59ca in ffs_blkfree () #13 0xc02b59bf in indir_trunc () #14 0xc02b5455 in handle_workitem_freeblocks () #15 0xc02b25ba in process_worklist_item () #16 0xc02b22e0 in softdep_process_worklist () #17 0xc024593e in sched_sync () #18 0xc01e21de in fork_exit () (kgdb)Received on Fri May 02 2003 - 14:14:50 UTC
