Description Adam Williamson 2023-01-27 20:07:38 UTC 
grub2-2.06-77.fc38 seems to crash consistently in an openQA test which runs `grub2-mkconfig -o $(readlink -m /etc/grub2.cfg)`. The journal shows:

Comment 1 Adam Williamson 2023-01-27 20:32:54 UTC 
This breaks install: https://openqa.fedoraproject.org/tests/1722170

so marking it as a Beta blocker as a violation of "The installer must be able to complete an installation to a single disk using automatic partitioning" (and any other "install must work" criterion).

backtrace of crashed grub2-probe

Here's a backtrace of the crashed grub2-probe process. Note before the backtrace, gdb shows the message "142    ../grub-core/disk/diskfilter.c: Bad file descriptor."
Comment 3 Robbie Harwood 2023-01-27 22:47:50 UTC 
With new build, this no longer reproduces under local testing.
