Minimum information for kernel problems
! Familiarize yourself with the general bug reporting procedures
! first. All of that will apply.
!
When reporting a kernel panic or crash, please remember:
! - We need the console output on the screen. Capture it and
! save it. Serial consoles are best, but if you are on a VGA console you
! can scroll the console
! back and take readable pictures with a phone or camera.
! - If the kernel paniced we need the traceback. It may be
! displayed on the screen. If are at a ddb> prompt, type trace, If you are running SMP, use the mach ddbcpu N command for each of the N processors you have and repeat the trace command for each processor.
! - We need the process list. Use the command ps to get us that.
! Reports without the above information are useless. This is the minimum we need to be able to track down the issue.
Additional information you can send
! In some situations more information is desirable. Below are outlined some additional steps you can take in certain situations:
- ... XXX boot crash? XXX
- ... XXX show regs? XXX
!
- If your crash appears to involve filesystems The following additional things would be helpful
! - The output of the ddb> command show uvm
!
- The output of the ddb> command show bcstats
!
- The output of the mount command from your running machine, so we know what filesystems are mounted and how.
! - If you crash appears to involve hibernate/resume XXX
