Public bug reported:
On ubuntu 7.0.0-15-Generic Sata6gbps drives when attempting to mount on
Ubuntu 26.04 LTS on Asrock B850M Riptide motherboard results in link
speed issues starting at sata6gbps and degrading down to sata3gbps then
sata1.5gbps. Random drive disconnects, and eventual kernel panics making
using sata HDD drives unstable. Tested Drives, WD Red WDC
WD30EFRX-68EUZN0 and Seagate IronWolf NAS ST12000VN0007-2GS116. Both
drives exhibit identical behavior regardless of sata cable or ata port
on board. Attempting to manually mount causes immediate system crash.
Sata drives being connected also significantly increase boot times and
shutdown times aswell.
