I can confirm this with a Kubuntu Guest on a Kubuntu Host (both 22.04.1) Firefox will crash on average every 30 seconds, no matter what website you are on, the more you interact with it the faster it will crash.
Chromium will also crash occasionally, but far less often than Firefox. Some other apps have also crashed occasionally in the last 2 days and even the entire plasma shell in the guest has crashed a few times, black screen or frozen and once it was not even possible to shut down the guest with ACPI event anymore. Downgrading to the previous -46 kernel made all these problems disappear. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1988473 Title: Version 5.15.0-47 Breaks Virtualbox Win10 VM Status in linux package in Ubuntu: Confirmed Bug description: The updated linux kernel would not allow my Win10 VM to boot. Rebooting Ubuntu into the 5.15.0-46 version restored the avility to boot. The 47 version also corrupted the VM, so I had to use a backup. I don't know if the problem was really with new Intel microcode that was installed with the new kernel. VB kernel modules were updated by dkms with the new version 47 install, so that should not be the problem.
