Hi Robert and others, I just upgraded from 5.5 (stable btw.) to 6.1 and after 10 hours I got a nice panic. Does this look like some tty problem ? This is the machine which made that many problems with PREEMTION enabled in earlier releases of 5.x. Is it possible that I'm hitting now again the same bugs or is it clearly a tty related problem ? kgdb /var/core/kernel.debug /var/core/vmcore.6 #0 0xc0663002 in doadump () #1 0xc066355e in boot () #2 0xc06638b5 in panic () #3 0xc085c6b6 in trap_fatal () #4 0xc085c3bf in trap_pfault () #5 0xc085bfb5 in trap () #6 0xc0848bea in calltrap () #7 0xc0693b51 in ttymodem () #8 0xc0698362 in ptcclose () #9 0xc0638a6f in giant_close () #10 0xc06162bf in devfs_close () #11 0xc086dc1c in VOP_CLOSE_APV () #12 0xc06c87e2 in vn_close () #13 0xc06c974a in vn_closefile () #14 0xc06162e7 in devfs_close_f () #15 0xc0642cdc in fdrop_locked () #16 0xc0642c29 in fdrop () #17 0xc06411c7 in closef () #18 0xc063e329 in close () #19 0xc085c9f7 in syscall () #20 0xc0848c3f in Xint0x80_syscall () #21 0x00000033 in ?? () Previous frame inner to this frame (corrupt stack?) Unfortunaltly I get this with the debug kernel. Does one have to boot with the debug.kernel itself to get a trace which is usable ? kgdb /var/core/kernel.debug /var/core/vmcore.6 kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) kgdb: kvm_read: invalid address (0x21) Martin Blapp, <mb@imp.ch> <mbr@FreeBSD.org> ------------------------------------------------------------------ ImproWare AG, UNIXSP & ISP, Zurlindenstrasse 29, 4133 Pratteln, CH Phone: +41 61 826 93 00 Fax: +41 61 826 93 01 PGP: <finger -l mbr@freebsd.org> PGP Fingerprint: B434 53FC C87C FE7B 0A18 B84C 8686 EF22 D300 551E ------------------------------------------------------------------
