I noticed that this is still showing up on the list of release-critical
bugs, despite subsequent updates; and the bug tracking system thinks it
applies to Debian 11 'bullseye' and to testing/unstable, although the
report seems to be specific to Debian 10 'buster'.

If the crash Steve mentioned is the same one described in #990082
and #990190, then it should be fixed in version 1.37 and up, which
were included in later point releases of buster (currently version
1.38~1+deb10u1) and also included in the bullseye stable release
(currently version 1.38). Please could you confirm whether these newer
versions can boot on Oracle Cloud machines?

Thanks,
