@Matthew Ruffell (mruffell) Debian and Ubuntu virtualbox maintainer here. Some questions: 1) can you please try a ppa build with also a cherry-pick of ef40d28f17bd randomize_kstack: Remove non-functional per-arch entropy filtering instead of reverting?
If the issue is fixed with another cherry-pick and not by a revert it would be better 2)In the meantime, I will try and look through the virtualbox subversion repository to find where virtualbox fixed this to see if backporting a fix for virtualbox would be a better route to take. no need to do it, upstream rewritten all the code (for different reasons) and the bug is just not there anymore. Quoting upstream "7.0 is unaffected because of some code rewrite (without intending to avoid any such problem) but that's a widespread change which we won't make for 6.1." -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.15 in Ubuntu. https://bugs.launchpad.net/bugs/2073267 Title: Virtualbox Guru meditation on VM start caused by kernel commit in v6.9-rc4 Status in linux package in Ubuntu: Triaged Status in linux-signed-hwe-5.15 package in Ubuntu: Confirmed Status in virtualbox package in Ubuntu: Confirmed Bug description: It worked yesterday, but today I get a Guru Meditation trying to start some of my virtual machines. This shows up in VBox.log as "VCPU0: Guru Meditation -2708 (VERR_VMM_SET_JMP_ABORTED_RESUME)". I suspect this may have started due to a Linux kernel upgrade I installed this morning. A fresh VM with no disk shows the issue. Sometimes turning off the I/O APIC makes the issue go away, sometimes not. Turning off nested paging sometimes lets VirtualBox make a little bit of progress w.r.t. booting VMs, but that usually still crashes before the VM finishes starting.
