I just updated a VirtualBox Rawhide guest with latest updates which included the 5.11.0-rc2 kernel and the system hangs on boot (pic attached). The system was updated a few days ago so was reasonably up to date before today.
Booting the previous kernel 5.10.0-rc6 still works OK.
In case something weird happened in the update, I reverted to a backed up copy of the vm (also reasonably up to date) and updated kernel* and rebooted with the exact same results.
Is anyone else seeing this problem with VirtualBox guests?
I can confirm the issue. This is likely related to the vboxvideo driver, 5.11 has seen some cleanup of the gem/ttm and fb_helper code which vboxvideo uses and I believe that that has broken it.
I'm trying to see if a can pinpoint the exact bad commit and then I will report this upstream.
Can you please file a bug for this in bugzilla, using kernel as the component? :
