2.5.66 still exhibits this bug. It is very strange because I even tried to
compile a 2.5.66 kernel without at keyboard support and it still kill the Fn
key functionality, meaning that I cannot make presentations on my laptop
because I cannot switch the video output to the back of the laptop as I was
able to before.
This bug was introduced somewhere between 2.5.63 and 2.5.64. Was there any
work done on keyboard handling or interrupts or anything that could have
affected my Fn key between 2.5.63 and 2.5.64? Is there someone that I should
contact directly about this that is maintaining the interrupt handling on X86
or whatever is causing this. I am unable to narrow down the bug with the help
of BK as I have not been able to find a way to find and isolate the patch
that caused this. Even after talking to Larry McVoy about this, he suggests
that I need to know what file changed and caused this to narrow it down with
BK. BK, apparently, can randomly change the revision numbers in a way that I
cannot rely on them to be constant as I was under the impression in my last
email. Please, someone help me. BK is not easy to use for QA AFAICT.
If anyone knows anything about this, I am begging for some help in finding
this bug. I have also CCed the input driver maintainer, although I do not
believe that this bug is in the input layer. Please CC me if you reply to the
list.
