Hello, I have the same issue, with a NVME drive as well.
It looks like the segmentation fault comes from grub-probe, when called with --target=hints_string. Attached grub-probe.log is the output of the command that leads to a segfault. Trying with gdb doesn't give much more information, the call stack is: Program received signal SIGSEGV, Segmentation fault. __strcat_sse2_unaligned () at ../sysdeps/x86_64/multiarch/strcat-sse2-unaligned.S:46 46 ../sysdeps/x86_64/multiarch/strcat-sse2-unaligned.S: No such file or directory. (gdb) bt #0 __strcat_sse2_unaligned () at ../sysdeps/x86_64/multiarch/strcat-sse2-unaligned.S:46 #1 0x000055555555dd38 in ?? () #2 0x000055555555ca89 in ?? () #3 0x000055555555be76 in ??

() I'm not sure how critical it is either but as a workaround, it's possible to roll back to testing versions of the grub-efi-amd64-bin, grub-efi-amd64, grub2-common packages. Cheers, -- Beren Minor
