At this point, with the current PLL change, it looks like the number of 
affected systems would be smaller than would be with the previous PLL value.

So far we have not received additional reports of regressions caused by 
this patch, other than yours. So, perhaps, the it can be manageable with 
a DMI quirk approach. I went ahead and implemented the infrastructure, 
it's actually quite a small change, and does what I want (automatically 
alters the default value of the K1 disable flag).

Could you share the DMI IDs of your system, where the issue is observed? 
Most likely the sys_vendor, product_family and product_name, located 
under /sys/class/dmi/id would be the most useful. I can add them as an 
initial DMI table entry for v3 of this patch (or a follow-up patch).

Thanks!
