Comment 15 for bug 1910866

So bisecting between 5.8.18 (bad) and 5.11-rc3 (good).

The following results with the mainline kernel
v5.11-rc3/ PASS
v5.9.12/ PASS
v5.9.10/ PASS
v5.9.9/ MISSING
v5.9.8/ FAIL (could not boot long enough for full test)
v5.9.7/ FAIL (could not boot long enough for full test)
v5.9.2/ FAIL (could not boot long enough for full test)
v5.8.18/ FAIL

Note that 5.9.2, 5.9.7, 5.9.8 all crashed during either boot or logging in (but after performing REISUB they all entered the Dell BIOS/recovery stating that the hard disk could not be found, so I assume this is the same failure).

From these results it appears that between 5.9.8 and 5.9.10 it was fixed.
