Fair enough. It *is* more of a workaround rather than a real fix and an easy
workaround would be the kernel boot option anyway. As rightly pointed out
by one of the folks, it may just be me so no point changing stuff for all.

I'll try to provide as much info as I can to them, and hope more
users (or not) might report issues.

(No concern for me personally, I'm happy that it works well for me already)
