Snapshot 20220602 brings in the 5.18 kernel, but a message from Virtualbox maintainer Larry Finger indicates that this kernel doesn’t play well with the current version of VirtualBox:
rpm -q --changelog virtualbox | grep -iB2 1199803
* Fr Mai 27 2022 Larry Finger <Larry.Finger@gmail.com>
- Update fixes_for_kernel_5.18.patch to save and restore FPU status during interrupt.
The change fixes boo#1199803.
It’s fixed, all right! Thank you, Sauerland. I saw Larry’s mailing list post, but not the bug report. I dup’d in the 5.18.1 kernel, and everything seems to be working in VB as before.
