Hello all,

I found the latest Qemu release can't bootup the VM with latest guest kernel(>5.13).

The normal v6.0.0 release is good to bootup the latest guest kernel.

There are two issues were found
1. Guest kernel panic.
2. kvm disabled by bios

The panic log as below:

I also used the bisect to get the bad commit id: f5cc5a5c168674f84bf061cdb307c2d25fba5448

This issue is known issue? or some fixs are ready to fix those issues? thanks!

What's your qemu command line?

I'm also having a kernel crash (although I think mine is with a different
call stack) when using "-cpu host". The crash doesn't occur when I use
"kvm64" cpu type.
