Yeah, as I said in my other mail, there seem to have been some recent changes
to the ext4 driver with regards to crc32 which I wasn't aware of. Thus, your

Yes, please. I have not observed this issue myself yet, so I'm curios to
learn what the root cause is. I have recently booted Debian's 6.12.x kernel
on an UltraSPARC IIIi without problems, so this issue may affect fresh
