Re: Maybe we want to maintain a bad driver list? (Was 'Re: "bad tree block start, want 419774464 have 0" after a clean shutdown, could it be a disk firmware issue?')

SSDs are a different story:  there are so many models, firmware revisions
are far more diverse, and vendors are still rapidly updating their
designs, so we never see exactly the same firmware in any two incident
reports.  A firmware list would be obsolete in days.  There is nothing
in SSD firmware like the decade-long stability there is in HDD firmware.

It might still be worth having reports act as a counter. 0-3 might be
"not enough info", 4-7 might be "suspicious", 8+ might be "consider
yourself warned".

But the scale could be a problem due to the small sample size.

That's a good idea, I've started something on
https://btrfs.wiki.kernel.org/index.php/Hardware_bugs
using the mentioned WD and firmware as first exapmle.
