My laptop has been crashing quite a bit lately. Because its running X, I can't actually see anything in ddb. So I just type "boot dump" and wait for it to reboot. Every time I do this though, trying to look at the dump using gdb I get:
(gdb) target kvm /var/crash/bsd.3.core #0 0xd0448f25 in dumpsys () (gdb) bt #0 0xd0448f25 in dumpsys () #1 0xd0448bf6 in boot () #2 0xd02f00d4 in db_boot_dump_cmd () #3 0xd02efbd3 in db_command () #4 0xd02eff2e in db_command_loop () #5 0xd02f2dae in db_trap () #6 0xd044550b in kdb_trap () #7 0xd0455399 in trap () #8 0xd0200f26 in alltraps () #9 0x00000000 in ?? () The panics show up in /var/log/messages as: savecore: reboot after panic: free: duplicated freea and savecore: reboot after panic: amap_wipeout: corrupt amap Any ideas why the dumps I get are no good? This laptop has been upgraded to various snapshots several times over the last few years (currently its a may 10th snapshot), so I may have messed something up when upgrading at some point. Thanks Adam
