Thanks for taking care, unfortunately no improvement with 5.10.38-rc1 here.
So in case this is related to the .config, I'm attaching it. Hardware is, as said before, an old Thinkpad x200, vendor BIOS and no particular modifications. After disabling all vga/video/fbcon parameters I see the system suffers a kernel panic but unfortunately only the last 25 lines are visible. Possibly (typos are mine)
RIP: 0010:__domain_mapping+0xa7/0x3a0is a hint into the right direction?
This looks intel_iommu related, can you try boot with "intel_iommu=off" in kernel parameter?
Gotcha. System boots up fine then.

So it's caused by this commit[1], and it should be fixed by latest 5.10.38-rc1 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/l... [1]https://lore.kernel.org/stable/20210515132855.4bn7ve2ozvdhpnj4@nabokov.fritz...
