Hello everyone
I have a two-part question:
I have a minimally customized GENERIC kernel, with the only changes being:
options KDB
options KDB_UNATTENDED
options DDB
and 'sysctl debug.debugger_on_panic' shows:
debug.debugger_on_panic: 0
However, after a panic loading the vboxdrv.ko module, the machine did
not reboot automatically after reboot.
I meant automatically after panic. It's early, and I am apparently
unable to type a coherent thought...
Here are my questions:
1) Would enabling DDB in the kernel prevent an automatic reboot after a
panic?
2) Does the debugger wait for XX seconds of console inactivity before
rebooting? I was under the impression from the handbook that the
machine would instantly reboot and after dumping the crash to vmcore0.
Is this assumption incorrect?
Thanks in advance for any input.
Also, if this is helpful, the userland / kernel are from two days ago,
r193481:
FreeBSD orion 7.2-STABLE FreeBSD 7.2-STABLE #0 r193481: Fri Jun 5
01:55:06 EDT 2009 r...@orion:/usr/obj/usr/src/sys/ORION i386
Sorry for the noise... Disabling DDB from the kernel corrected the
reboot issue.
Unless I am misunderstanding how it is worded, it is unclear from the
HTML docs that DDB overrides KDB_UNATTENDED.
If I am misunderstanding, I apologize, but I'm more curious if I am
experiencing unusual behavior with DDB enabled.
