[14:07] <Guest45> I'm having KVM issues with a kernel update done on Thursday: linux-image-5.15.0-47-generic.  It's causing my VM guests to have segfaults in random processes.
[14:22] <Guest458> Someone else noticed the issue here I think: https://forums.virtualbox.org/viewtopic.php?f=7&t=106954
[15:02] <Guest458> I guess I'm blaming this: USN-5594-1 update, but I cannot prove it except that I have issues with it, and zero issues with previous kernel.
[15:07] <sbeattie> h/me pokes some kernel people
[15:37] <sbeattie> Dunno if guest458 will come back, but it would be good to know if the 5.15.0-48 kernel in jammy-proposed has the same issue, if it as actually affecting KVM users, and what processor is in the system.
[15:38] <sbeattie> LP:#1988473 looks to be the virtualbox bug
[15:38] <sbeattie> If it is also affecting kvm, a new launchpad bug against the linux package would be helpful.
[15:39] <sbeattie> (I'm not able to reproduce it yet with some kvm stress testing here)
