Hi!
Any thoughts on this one? We should come back from resume in 30-row mode,
shouldn't we?
Well, current state of video resume is "we are happy to see anything
at all".
HW info
Using vga=0xf07, default8x16 font, display has 30 lines
On powerup from S3 console has only 25 lines but still scrolls
at 30 lines. Setfont historically fixes it.
Tested with 2.6.10, 2.6.11-rc1: OK
Tested with 2.6.11-rc2-Vanilla and 2.6.11-rc[234]+swsusp2.
When using setfont, screen goes blank. Power up after S3
returns console in 25 lines mode with 30 lines scroll.
Several attempts - same result.
So... screen goes blank even when suspend is not involved, right?
Sounds like a bug to me ;-).
Another bug I see only on this HW and only with 2.6 is that
when - and only when - using gentoo emerge --usepackage in
text console, scroll area resets to _25_ when portage
"dumps" the (binary) package contents which scrolls pretty
fast. I was unable to reproduce this in any other way.
Tried also echo loop in bash but perhaps it is too slow
or not random enough. Note that 2.4.2[789] no problem.
Well, dumping random stuff to console can produce funny results. I'd
call that normal. Try cat /dev/urandom, that should be "enough
random".

I am also getting strange effects. I boot into 2.6.11-rc4 and the
console fonts looks fine. Come back a day later and the console font has
corrupt characters. E.g. Displays a "D" instead of an "L" and stuff
like that. It is mostly readable, except for a few characters.
It is only the local console that is corrupted. ssh into the box
displays correct characters, so all I can assume is that the VGA console
is being programmed with different characters. The bad characters also
survive a soft reboot( During BIOS boot up), until the linux kernel
starts booting, and then it switches to a good font.
