Fwd: Kernel 5.11 crashes when it boots, it produces black screen.

[Bagas Sanjaya]

Hi,

I noticed a regression report on Bugzilla ([1]). As many developers don't
have a look on it, I decided to forward it by email. See the report
for the full thread.

Quoting from the report:

> Same as in https://bugzilla.kernel.org/show_bug.cgi?id=212133, but not StoneyRidge related. I have same issue in 5.11.9 kernel, but on Renoir architecture. I have AMD Ryzen 5 PRO 4650U with Radeon Graphics. Same stuck on loading initial ramdisk. modprobe.blacklist=amdgpu 3` didn't help to boot. Same stuck. Also iommu=off and acpi=off too. 5.10.26 boots fine. I boot via efi and I have no option boot without it.

Azamat, can you try reproducing this issue on latest mainline?

Anyway, let me add this regression to regzbot:

#regzbot introduced: v5.10..v5.11 https://bugzilla.kernel.org/show_bug.cgi?id=212579
#regzbot title: Booting kernel on AMD Ryzen 5 PRO stucks in loading initrd

Thanks.
