Main difference is that I notice when the box (-CURRENT from 29 May, GENERIC kernel, UP) crashes. :-p Not being a -CURRENT guru, I haven't decided if I'm going to try Tor Egge's patch or just slug it out to try to finish fixing make release (which is my main goal at this point). Just as an FYI, here's the tombstone and a stack trace in case it's useful to anyone. Cheers, Bruce. -----8<-----8<----- Data modified on freelist: word 2 of object 0xc1985a00 size 52 previous type pagedep (0xd6adc0de != 0xdeadc0de) Fatal trap 12: page fault while in kernel mode fault virtual address = 0xdeadc0e8 fault code = supervisor read, page not present instruction pointer = 0x8:0xc0376ab8 stack pointer = 0x10:0xcba7fb9c frame pointer = 0x10:0xcba7fb9c 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 = 17 (swi3: cambio) kernel: type 12 trap, code=0 Stopped at worklist_remove+0x1c: cmpw $0,0xa(%ecx) db> trace worklist_remove(deadc0de) at worklist_remove+0x1c free_diradd(deadc0de) at free_diradd+0x26 free_newdirblk(c1396b70) at free_newdirblk+0x32 handle_written_inodeblock(c241a300,c64135d8) at handle_written_inodeblock+0x2b2 bufdone(c64135d8,cba7ff40,c0136a1b,c64135d8,c1394400) at bufdone+0x101 bufdonebio(c64135d8) at bufdonebio+0xe dadone(c127f400,c1394400) at dadone+0x1fb camisr(c048ccd4) at camisr+0x1c5 ithread_loop(c0e48980,cba7ffa8) at ithread_loop+0x2bf fork_exit(c022c118,c0e48980,cba7ffa8) at fork_exit+0xb4 fork_trampoline() at fork_trampoline+0x8 db> --==_Exmh_934798962P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.5 (FreeBSD) Comment: Exmh version 2.3.1+ 05/14/2001 iD8DBQE7FSHe2MoxcVugUsMRAp2UAJ45yxgX4uXmQ4wiOMz1LZIZHGGL3wCeJWN+ aHXJyI7/mEBIHSQ+2YfU5AU= =fhrV -----END PGP SIGNATURE----- --==_Exmh_934798962P-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
