Thank you for the report, and RedHat reference. Which says:
- Fault introduced by 2.06-2.fc34
- Works by regressing to 2.06~rc1-3.fc34
- Hoped for fix in 2.06-9.fc36 [feedback awaited]

How our current 2.06-1.1 relates is unclear. Note that the attached error output sample is 32-bit, the related RH bug is for x86.

Assigning this to tv, who maintains grub2.
