Debian 11 installer crashed and reboot

[John Mok <a9121431@gmail.com>]

Hi all,

Tried to install Debian 11 guest using netinst, but the installer
crashed and reboot automatically.

 Host: Xen 4.11.4 on Debian 10
Guest: Debian 11 (kernel 5.10)

Here is the steps to reproduce the problem:-
1) Either guest BIOS or OVMF boot
2) Select "Expert install" on installation menu

Then, the guest crashed and reboot.

Another try with the installer on Debian Live 11, it immediately
crashed and reboot.

Is it a installer bug or something ?

Thanks a lot.
