The last kernel to successfully boot on here is 4.19.x, while anything newer exhibits the same stuck processes - and indeed, blacklisting the myrb and myrs drivers allows 6.1 to boot on this machine. > > I know this card is functional, as I do have two drives attached to it, and both it and the drives work fine in 4.19 and older kernels, so the issue seems to be with the newer myrb/myrs drivers. Is there a chance of fixing the current drivers, or, at worst, reintroducing the old deprecated DAC960 driver back into the kernel? I'm not absolutely tied to using that driver, other than 'it just works' for this card.
