PVE 7.2 - Avago MegaRAID broken?

[Eneko Lacunza]

Hi all,

Today we installed PVE 7.1 (ISO) in a relatively old machine.

Installation was fine and Proxmox has booted OK. But after configuring 
non-subscription repository and upgrading to PVE 7.2/kernel 5.15, 
Proxmox won't boot anymore:

Kernel will print lots of messages like

"DMAR: DRHD: handling fault status reg 3"
"DMAR: [DMA Read NO_PASID] Request device [02:00.0] fault ???? 4b311000 
[fault reason 0x06] PTE Readaccess is not set.

(???? there are some missing chars in photos I shot, sorry).

After about 2,5 minutes, it would open a shell in initramfs, complaining 
pve vg was not found and "Gave up waiting for root file system device".

I suspected of a faulty controller first, but after booting with 5.13 
kernel (even the latest one as of today, -6) all was fine again.

We have removed 5.15 kernel, and rebooted 2-3 times, all is good now. :-)

Controller is

Avago MegaRAID SAS-MFI BIOS
Version 6.36.00.2 (Build Sep 11, 2017)
HA -0 (Bus 2 Dev 0) AVAGO MegaRAID SAS 9341-4i
FW package: 24.21.0-0025

Product AVAGO MegaRAID SAS 9341-4i  is listed as Revision 4.680.01-??? 
(shot cut there, sorry)

Controller has 3 WDC Gold 4TB in RAID5 attached.

This is worked-around now, but I'm starting to worry about latest 5.15 
kernel in PVE... :-)

Thanks
