Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting for once, to make this easily accessible to everyone. CCing a few lists and people. Greg is among them, who might know if this is a known issue that 6.6.4-rc1 et. al. might already fix. If that is not the case I guess we might need a bisection between 6.6.1 and 6.6.2 know if mainline is affected might be good, too.
