Greg,
I've done 5 upgrades so far without any issues. This is the first one
that has a problem and after some experimenting it looks like the kernel
is identifying both the analog and digital ports and making the digital
display the primary. I use a KVM switch and needless to say it's a
royal pain to have to switch back and forth to accommodate this one
host. Like you I settled on using th3 previous perfectly working 7.3
kernel, not optimum but it does work.
I've also decided to get a graphics card in lieu of the on-board
graphics card in the hope that that will solve the issue with the 7.4
kernel.
Agreed you do get used to these upgrades working seamlessly and it's a
bummer when occasionally things don't work out exactly as planned.
