Problem:
If I upgrade from grub 2.02-pve4 to anything newer (in Jessie or Stretch repos), after a reboot the system will freeze when attempting to boot grub, this freeze happens before any grub menu or rescue shell.
There are no errors from grub when installing new versions, and no errors are printed to the console when booting from disk, grub just does not appear to load at all (viewed from iDrac console). However grub 2.02-pve4 and earlier work as expected, I have tested this with ext4, xfs, and zfs as the root filesystem.
I have also verified that on Debian 9 I experience the same problem.
My current workaround is to install Proxmox 4.1 (last iso that has a working grub), pin the grub packages, and then upgrade to 5.0.
System:
Dell PowerEdge R710, with an LSI/Avago 9211-8i (IT mode) HBA - booting from BIOS mode.
All firmware is up to date on both the R710 and the 9211-8i as of yesterday (7/26/2017).
I have run hardware diagnostics and I have not found any errors with the physical components of the server.
Attached are some logs with more details on my hardware, but I'm not sure how useful they will be.
Any help or advice on troubleshooting would be appreciated.
