Bug 1322225

Dear Ji,

thank you for your bug report.

Beaker detects Kernel panics and sets the corresponding recipe status to Aborted with the result of PANIC. Looking closely into the console log of your job, it looks like the kernel was unable to raise a Panic:

RIP  [<ffffffff81469f6d>] skb_under_panic+0x5d/0x70 
 RSP <ffff880832457818> 

and then reboots.

There is nothing Beaker can detect here, since the logs don't show any information of a Kernel panic.

Thus I think this is not a bug and I'd like to close this as CLOSED NOTABUG.

Can we make beaker support it? Here is the following kernel crash message:

Dear Ji,

the crash message you've posted is not a kernel crash, but just a kernel BUG. Beaker can recognize this as well but it doesn't mean that it will halt the recipe. The actual crash would halt the recipe as I explained above.

There is nothing more to support here, since it is already supported.

Specifically, the kernel "BUG" traces will be captured by rhts-report-result (report_result function) when your task reports any result. It will show up as a failure in the dmesg check.

But in this particular case, the kernel BUG was printed and then the machine immediately rebooted -- so the dmesg checks never had a chance to finish because it crashed before rhts-report-result was even reached.

Hi Roman & Dan,

Got it. Many thanks for your comments!
