Thank you for narrowing down the bug to a certain patch level. (The ZZZ part of
Version XXX.YYY.ZZZ)
That really saves a lot of time on my end.
I will get a patch ready for testing by tomorrow.
It will likely remove some of the code within the viaIGAInitCommon function for
testing purposes, so that I can narrow down further to determine which hardware
register access is the offending party here.
In the meantime, there will be a new RC (RC5) that is not really related to
your bug fix.
The patch will be generated against that version, although it might still work
with RC4 or RC3.
Hopefully, by RC7 or RC8, it will be a release version.
