Comment 1 jospezial 2020-12-16 07:12:58 UTC
The log is from host?
Tell us more about the VMs you tried.
Try the patches for the VM side if it is a linux VM.
https://www.virtualbox.org/ticket/20055
You have to adapt the path for gentoo packages in the patches.
Comment 2 Alexey Shevchuck 2020-12-16 07:54:31 UTC
Yes, the log is from host. I'm starting Win10, and during VM loading host gets this crash.

I.e. VM was not fully loaded when this crash happens (VBox load gauge was on 20%).

Crash happens every time I'm trying to start VM.
Comment 3 jospezial 2020-12-16 12:48:53 UTC
please provide output of emerge --info
Comment 4 jospezial 2020-12-16 12:56:40 UTC
in the meantime you can search at

Comment 5 Alexey Shevchuck 2020-12-16 13:15:46 UTC

Comment 6 Alexey Shevchuck 2020-12-16 13:16:53 UTC
Yes, look like it's better to address problem to upstream. Initially I had an idea this may happen because of the patch, but the patch is identical to the one attached to the ticket.
Comment 7 Jonas Stein gentoo-dev 2020-12-16 15:41:20 UTC
please add a link to the upstream report here
Comment 8 Alexey Shevchuck 2020-12-16 18:51:31 UTC
I added comment to existing ticket => https://www.virtualbox.org/ticket/20055#comment:10
Comment 9 Adjudicator Darren 2021-01-31 02:46:30 UTC
CONFIG_DEBUG_SPINLOCK=y is what's causing the crash, but it's unclear if it's
a kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=211469
or a virtualbox bug: https://www.virtualbox.org/ticket/20163

So far, I'm using CONFIG_DEBUG_SPINLOCK=n to avoid the crash, but I'd like to have it be =y

Any ideas on what to do next to figure out what's the cause? I have the time and willingness, just need the brains :D
