--- Comment #55 from Samuel Wolf (samuelwolf85@googlemail.com) ---
We see this abort request / hang on Debian 12 with the ASR8805 two or three
months ago.
Since this was not the newest server we replaced this system because we thought
this
was an hardware issue.

[two month later]

But now, this week we upgraded the next server with ASR8805
from Debian 11.8 to 12.4 and saw exactly the same issue (Debian 6.1.67-1).

This could not be the same hardware error, so we found this bug
report and opened on at Debian bug tracker [1].

Salvatore build a test kernel [2] and we fired up the old "faulty" server for
testing.
With the new knowledge we was able to reproduce [3] this with an ASR8805 raid6
and 58TB LUKS drive.

luksOpen and mount reproduce this every time with kernel 6.1.67-1 and need ~ 1
minute (because the hang and reset request, I guess). Now booting into
Salvatore's test kernel (6.1.67-1a~test) and tried the same again, no issue and
the luksOpen mount was really quick.

This bug was more serious than I guess and it needed some time to get this
puzzle together.
