#75841 — Bug#1014394: linux kernel 5.10.0-15 on virtualbox host causes random process crashes in guests

package: linux-image-5.10.0-15-arm64
version: 5.10.120-1

i am running virtualbox 6.1.34 from the virtualbox.org repo on a debian 
11.3 host. the guest also runs debian 11.3.

when both host and guest run the latest stable kernel 5.10.0-15 
(5.10.120-1) i get random process crashes in the guest when having 
significant i/o for longer than a few seconds on the host.

i.e., when i do a

  # mv <large file> <destination>

or even a

  # md5sum <large file>

or anything that causes significant i/o traffic on the host, the guest 
first starts with complaining:

Jul 01 20:44:49 vmguest kernel: hrtimer: interrupt took 21312191 ns
Jul 01 20:45:20 vmguest kernel: clocksource: timekeeping watchdog on CPU0: 
kvm-clock wd-wd read-back delay of 816732ns
Jul 01 20:45:20 vmguest kernel: clocksource: wd-tsc-wd read-back delay of 
2540783ns, clock-skew test skipped!

and eventually guest processes start to randomly crash, e.g.:

Jun 30 20:17:01 vmguest kernel: traps: sh[250946] general protection fault 
ip:7fb0c341708e sp:7ffec3154378 error:0 in 
libc-2.31.so[7fb0c33a6000+14b000]
Jul 01 00:00:02 vmguest kernel: traps: hostname[253617] general protection 
fault ip:7f905f2b24a6 sp:7fff44a30e30 error:0 in 
libc-2.31.so[7f905f299000+14b000]
Jul 01 00:53:01 vmguest kernel: traps: wget[254290] general protection 
fault ip:7f934bc23fda sp:7ffd716954d0 error:0 in 
libtasn1.so.6.6.0[7f934bc1a000+c000]

if i switch to kernel 5.10.0-14 (5.10.113-1) on the host (the guest kernel 
remains 5.10.0-15), then the random process crashes in the guest disappear, 
although the complaints from hrtimer and clocksource still remain, but 
significantly less often.

i started a thread in the 'debian-user' mailing list:
https://lists.debian.org/debian-user/2022/07/msg00043.html

thank you for looking into this!

greetings...

#75845 — Bug#1014394: Also Affected - linux kernel 5.10.0-15 on virtualbox host causes random process crashes in guests

Hello,

I am also affected by this same bug.

I run Firefox in a virtual machine and if I am running the
5.10.0-15-amd64 kernel on the virtual host, then Firefox crashes
regularly in the virtual guest.

However, if I run the 5.10.0-14-amd64 kernel on the virtual host, then
I see no crashes.

In both cases the virtual guest is running the 5.10.0-15-amd64 kernel

This is on Debian Bullseye

VirtualBox packages are from Fasttrack
virtualbox       6.1.34-dfsg-3~fto11+1            amd64
virtualbox-dkms  6.1.34-dfsg-3~fto11+1            amd64
virtualbox-qt    6.1.34-dfsg-3~fto11+1            amd64

Kernels are the standard Debian kernels from stable (both host and
guest)
linux-image-5.10.0-14-amd64      5.10.113-1       amd64
linux-image-5.10.0-15-amd64      5.10.120-1       amd64

I have seen this issue on two separate systems, so I do not think it is
hardware related.

Happy to do any testing or provide any logs you can suggest.

Regards,

Richard

This indeed looks like an upstream regression between 5.10.113 and 5.10.120.

What surprises me are the time gaps between those GPF messages, ~3.5h and 50m, 
but not within the same second/minute. What happens between those time stamps?

If there are more messages around those GPF messages, it would be useful to 
share those as well.

In Stable-Proposed-Updates there is a 5.10.127-1 version and it would be 
useful to test whether the issue happens with that version too.

#75848 — Bug#1014394: Stable Proposed Updates Kernel

Hello,

I have installed the Stable-Proposed-Updates kernel on the virtual host
(linux-image-5.10.0-16-amd64 - 5.10.127-1) and I am still seeing
Firefox crashing frequently in a virtual guest running on this host.

I do not see any messages logged in kern.log when the whole of Firefox
crashes, but I do see the following messages when individual tabs in
Firefox crash (these tab crashes also happened with 5.10.0-15-amd64 -
5.10.120.1 but not with 5.10.0-14-amd64 - 5.10.113-1).

These are from the virtual guest however, not the host.  I do not see
any errors logged to kern.log on the host (even though that is the
system running the problematic kernel).

https://wiki.debian.org/DebianKernel/GitBisect describe a/the way to narrow 
down the specific commit that caused the regression.
Knowing that *really* helps to pinpoint the issue and would also help to 
determine which upstream (sub)project to contact about this issue.

I assumed these errors occurred in 1 boot session and having the FULL dmesg/
kern.log from *that* session would be useful.
Don't 'grep' the messages which you think are relevant. Often times there are 
other messages which give important clues to experts (which I am not), which 
seem irrelevant/harmless to you and me.
I'm guessing this bug should be sent upstream and they will (highly) likely 
ask for a full dmesg/kernel log.
(I'm merely trying to collect as much useful information as possible)

HTH,

I am also affected by this issue.

I cannot use my VM images anymore on this kernel version.
The Windows10 guest randomly crashes with:

As Virtualbox uses it's own kernel module, we can't provide any help.
You need to ask them for a fixed version to work with that kernel
version.

Or you can use the included kvm support.

FWIW, I'm running a test build[1] of VirtualBox with the -15 kernel on
the host.  I, too, had the problem of Firefox crashing regularly with
VirtualBox 6.1.34, but things seem stable with VirtualBox 6.1.35
r151864.

Thanks Mike,

I have upgraded to the test build of VirtualBox (6.1.35) and I am not
now seeing Firefox crashing in the virtual guest.  Both host and guest
are running 5.10.0-16-amd64 - 5.10.127-1.  So, I guess this is not a
kernel bug so much as a 'incompatibility' between these kernels and the
older versions of VirtualBox.

Regards,

Richard

Dear Maintainer,

VirtualBox (6.1.35) fixes the crashes on my system too.
