proxmox 8.x and megaraid_sas issue

[Romainp]

Hi!
I post here in a desesperate need for help or advices...
I am the proud owner of a proxmox lab that was working fine during those last months on my
SuperMicro X9DRE-TF+ with 200G of RAM
I have a Perc H310 controller configured with 4 x 1T discs in RAID 10 config

This setup was working fine until those days... Maybe there was some updates on the kernel but since then, my controller does not work anymore..
I mean, I have hard time to boot correctly until I set some parameters in grud (intel_iommu=on iommu=pt pcie_aspm=pff acpi_enforce_resources=lax) but even then, the megaraid_sas keep crashing some errors in the logs and obviously the mounts are not available..
I have tested with 2 other controllers and got the same results.
For the fun, I have boot systemrescuecd 11.01 and I was able to mount to access the drive with no problem which lead me to think that something isnot working correctly with the megaraid_sas driver provided by proxmox on the recent release.

I can post logs if I can but I am wondering what can I do from here?

Any advices is welcome.
Thanks

Yes, megaraid_sas is broken with kernel 6.8. A H310 with mptsas-driver (ZFS-RAID) works fine, H330 with megaraid-sas have no disks.

Update: Fixed with Kernel: Linux 6.8.4-3-pve

...and again brocken with Linux 6.8.12-4-pve - I'm using the Lenovo ThinkSystem RAID 530-8i PCIe 12Gb Adapter (= megaraid_sas) which was working fine with Proxmox V. 8.1-2 (Kernel 6.5) but installing V. 8.3-1 is not possible with this Raid adapter. The installer does not find a harddisk. So, back to kernel 6.5? Is this possible/running with Proxmox V. 8.3?

Just tried: same with latest kernel Linux 6.8.12-7-pve - very disappointing that proxmox is not able to fix that for a really big group of Raid controllers!
