kernel panic CentOS 6.2 guest - init_tsc_clocksource
Hi All,
I've been using VB for a few weeks now and lately all my CentOS 6.2 x86 guests (Windows7 hosts) stopped working. The kernel panics with divide_zero error in init_tsc_clocksource on startup. Sometimes if I reboot over and over again it makes it through, but not always.
I'm stumped what could be causing this. I tried to change the kernel clocksource to 'jiffies' and 'acpi_pm' in grub.conf, but that doesn't appear to make any difference. Is this something new to the latest kernel: Linux centos32-vm1 2.6.32-220.7.1.el6.i686
Thanks for ANY help!! I'm dead in the water until I can figure this out.
Thanks!
Corey.

I would try the divider=10 in the boot line and see if that settles it down.

Didn't make any difference...

Does this only happen during a reboot (warm boot)? Does it happen/not happen on a shut down (cold boot)?

It appears to only happen on a cold boot. I attached a screenshot of the kernel panic, maybe there's something else that jumps out at you.

Re: kernel panic CentOS 6.2 guest - init_tsc_clocksource
I do see this but just the opposite. If I do a reboot it will hang, but if I do a shut down and start it works. I have reported a ticket about this Bugtracker ticket #10427 if you would like to add your information.

I added my info to the ticket. Good hunting.

Re: kernel panic CentOS 6.2 guest - init_tsc_clocksource
This just hit me for several RH-based VMs. Some googling found the answer on the centos forums. (I'd post a link, but I just created my account, so the rules block it.If you google for "Kernel panic with cent os kernel 2.6.32-220.7.1.el6.i686 virtualbox", it's the 2nd hit. First is this thread. )
To fix it, I had to change the chipset from PIIX3 to ICH9 and turn on IO APIC. This worked for several VMs that were experiencing the issue;
Oracle Linux: 2.6.32-300.21.1.el6uek.x86_64
Oracle Linux: 2.6.32-300.21.1.el6uek.x86_64
CentOS:2.6.32-220.13.1.el6.x86_64
All VMs are 64-bit on a WinXP host.

ICH9 is still experimental and has issues. Actually it has more issues than the annoyance of not being able to cold boot the machine.
Re: kernel panic CentOS 6.2 guest - init_tsc_clocksource
I wasn't aware of that. Thanks for the heads-up!
I went with it since my affected VMs wouldn't boot at all. Not cold boot or reboot.

I was having the same issue when I would install 6.2 and then yum update to the .300 kernel.
Changing to the ICH9 Chipset seemed to do it.
Thanks

I'll add the infamous "me too". This fix was necessary to boot centos 6.2 kernel 2.6.32-220.23.1.el6.i686. I didn't experience this with any earlier kernel.jfmatth wrote:I was having the same issue when I would install 6.2 and then yum update to the .300 kernel.

Re: kernel panic CentOS 6.2 guest - init_tsc_clocksource
Could you also try if using the normal PIIX3 chipset with activating HPET (VBoxManage modifyvm VM_NAME --hpet on) works as well?
