Description Matthias Schroder 2010-04-28 12:40:50 UTC
Description of problem: kernel panic during initial package installation

Version-Release number of selected component (if applicable): 2.6.32-19.el6.x86_64

How reproducible: 100%

Steps to Reproduce:
1. Try to install
Actual results: panic

Expected results: installed RH6beta

Additional info: I use a kickstart file with a somewhat complex kickstart file, allowing me to boot several different OSes. That works if I install the i386 version, but fails when I try to install x86_64.

screen shot of traceback

I don't know how to 'classify' the panic, but I have a screenshot of the trace. Unfortunately I did not have a tripod for my phone, so the quality is not the best. But it should be sufficient.

Comment 5 Prarit Bhargava 2010-04-30 14:23:11 UTC
Matthias,  unfortunately the beginning of the panic is not on the screen.  Is there any chance you could hook this system up to another system via a serial connection?


Comment 6 Matthias Schroder 2010-04-30 15:45:50 UTC
Hi Prarit,

yes, that can be done. But I have no idea how to do the necessary configuration, can you point me to some documentation?

log from serial console

Hi Prarit,

the log from the serial console is attached. I was struggling because the PC next to the one in question has a non-working serial port :(

I hope the log is helpful.



Comment 9 Prarit Bhargava 2010-05-03 18:16:06 UTC
Hi Matthias,

The log was useful -- thank you for providing it.  When reporting a panic or an oops, it is *very* useful for you to supply us with a console log.  It makes debugging a lot easier :)

The good news is that your problem has already been fixed by another engineer in BZ 574570.  A work-around for your issue is to install and boot with "nmi_watchdog=0" as a kernel option.

Also, if you can boot the system (and I know in this particular instance you were unable too) supplying a 'sosreport' (type sosreport on the command line) for the system is also useful.  It provides us with a lot of information about your system and we use it to determine what could be broken.

Thanks again,
