Hi, this is your Linux kernel regression tracker.
I noticed a regression report in bugzilla.kernel.org that apparently affects 6.2 and later as well as 6.1.13 and later, as it was already backported there.

[FWIW: That's "ata: ahci: Add Tiger Lake UP{3,4} AHCI controller" from Simon Gaiser]
I sent a revert with cc: stable.
