4 TiB WD SN700 drives drop off of Sonnet Card

[Justin Piszcz]

Hello,

Kernel: 6.12.73
Distribution: Debian Stable Trixie

There are long outstanding issues with these WD Red SN700 4TiB drives
with an ASUS FlahsStor Gen1.

I have 16 drives on two x8 Sonnet boards and the same issue is
occurring across two different platforms.  Are these drives completely
defective when used in a software raid configuration?

Does anyone have a specific kernel parameter to make these drives work
without dropping off the bus— or is it time to retire/replace these
drives?  On various forums the below parameters had been tested
previously and did not help.
