I have tried again with the 5.8.0 kernel and btrfs-progs v5.7 (which
I've compiled statically on a different machine and used only for btrfs
device remove and btrfs check). The system still goes read-only when I
attempt to remove the failing drive, but it doesn't oops in this
version.

This version of btrfs check finds many more problems, however the
'checksum verify failed' line looks supicious: instead of `found
BAB1746E wanted A8A48266` it prints `found 0000006E wanted 00000066`
like if the checksums had been truncated to 8 bits before printing.

I still haven't tried disconnecting the failing disk.

Thanks again.
