After fixing user core dumps > 2 Gb, I'm now in search of getting my kerneldumps to work..... opteron# uname -a FreeBSD opteron.digiware.nl 5.2-CURRENT FreeBSD 5.2-CURRENT #17: Fri Jun 4 15:2 9:43 CEST 2004 wjw@opteron.digiware.nl:/usr/obj/home2/src/sys/OPTERON.amd64 amd64 This is what I do: ---------------- ctrl-alt-esc db> call doadump Dumping 2046 MB Dump failed. Partition too small. 0x23 ---------------- Which is sort of bogus since the swappartition is "only" 5GB and there's only 2 GB of memory in the box. Trying to get a panic: ----------------- db> panic panic: from debugger at line 453 in file /home2/src/sys/ddb/db_command.c cpuid = 1; Stack backtrace: backtrace() at backtrace+0x17 __panic() at __panic+0x1e4 db_panic() at db_panic+0x1e db_command() at db_command+0x24e db_command_loop() at db_command_loop+0x88 db_trap() at db_trap+0xb5 kdb_trap() at kdb_trap+0x151 trap() at trap+0x3bd calltrap() at calltrap+0x5 --- trap 0x3, rip = 0xffffffff80393d45, rsp = 0xffffffffb19d4ae0, rbp = 0xffffff ffb19d4b00 --- Debugger() at Debugger+0x4d scgetc() at scgetc+0x43f sckbdevent() at sckbdevent+0x201 atkbd_intr() at atkbd_intr+0x26 atkbd_isa_intr() at atkbd_isa_intr+0x1a ithread_loop() at ithread_loop+0x229 fork_exit() at fork_exit+0xe5 fork_trampoline() at fork_trampoline+0xe --- trap 0, rip = 0, rsp = 0xffffffffb19d4d00, rbp = 0 --- boot() called on cpu#1 syncing disks, buffers remaining... panic: pmap_invalidate_range: interrupts dis abled at line 654 in file /home2/src/sys/amd64/amd64/pmap.ccpuid = 1; boot() called on cpu#1 Uptime: 3d13h29m59s ------------------- And a hard reset is required..... 2 questions: 1) Are others with amd64/2Gb memory able to get kerneldumps??? 2) Where should I start looking to get thigs fixed.... --WjW
