Ubuntu 20.04 won't boot with Kernel > 5.13.0-32

[NickC10]

With parallels 17.1.1 Ubuntu 20.04 is hanging on boot with kernels 5.13.0-35 and 5.13.0-37. 5.13.0-32 works.

With parallels 17.1.1 Ubuntu 20.04 is hanging on boot with kernels 5.13.0-35 and 5.13.0-37. 5.13.0-32 works.

Typo in the kernel tag -- 5.13.0-36 not 37.

A number of folks, including me, are getting this issue. There are already a couple of threads opened in the last week about this. Clearly something has recently broken either in the linux kernel (unlikely) or in Parallels (more likely) - we're hoping that as it was quickly introduced, it can be just as quickly addressed (but then, I'm an optimist ).

Further to the above, the problem doesn't seem to be specific to a single kernel version, but to a particular configuration of kernel. I have a VM which installed as Ubuntu 18.04 (worked fine - kernel version 4.15) then failed to boot when upgraded to 20.04 (kernel 5.4) but booted OK when previous kernel selected in grub.

Yes, same problem

Nearly the same issue here:

• hanging on boot with kernel 5.13.0-35
• fine on boot with kernel 5.13.0-28

(Parallels 17.1.1, Ubuntu 20.04)

I see there is a fix for this with UTM (implying this is a virtual machine, not a kernel issue?).

This is likely https://lkml.org/lkml/2022/3/14/2 for those who like to poke the kernel inside.

Yes that commit revealed the bug in parallels I posted the reason in
https://forum.parallels.com/threads/official-ubuntu-20-04-live-server-does-not-boot.356891/
However I've been unable to get past first line support.
