NetBSD 5.1_RC1 panic, unknown reason
Hi,
the 5.1_RC1 kernel on my HP dc7700S just panicked for no apparent
reason. There was no pkgsrc software installed, i just configured some
basic components from base like powerd, ntpd and sshd. Console runs at
115200 baud over com0 and at the moment it happened there was no user
logged in. After some time, I reconnected and found myself in DDB
(which is funny, since I had ddb.onpanic?=0 in /etc/sysctl.conf):
db{0}> bt
breakpoint() at netbsd:breakpoint+0x5
comintr() at netbsd:comintr+0x53a
Xintr_ioapic_edge8() at netbsd:Xintr_ioapic_edge8+0xef
--- interrupt ---
x86_mwait() at netbsd:x86_mwait+0xd
idle_loop() at netbsd:idle_loop+0xe9
db{0}> sync
syncing disks... piixide0:1:0: lost interrupt
type: ata tc_bcount: 12288 tc_skip: 0
piixide0:0:1: lost interrupt
type: ata tc_bcount: 12288 tc_skip: 0
piixide0:1:0: lost interrupt
type: ata tc_bcount: 512 tc_skip: 0
piixide0:0:1: lost interrupt
type: ata tc_bcount: 512 tc_skip: 0
I wasn't able to read the message which lead to the bt above. And a
crash dump, as you can see, didn't work out either. Also the system
hung after the lost interrupts and had to be power cycled.
I guess all that is of no great value without a crashdump.
