So, here we are - 6 (six) months later - and i still have "an issue".
And no, there is no new BIOS for my motherboard.
I do still regularly apply my patch to kernels to have this fixed.
I would, once more, ask if this can be included in regular driver? It
does not have to be enabled by default, module option which would turn
this on would be sufficient.
