New subject: My Asus P2B-LS is still having fun with coreboot/SeaBIOS/flashrom. Now I have questions.

31 Dec 2021


      Hi
...
I have to calmly tell it "laptop=this is not a laptop" and then it works as usual. I don't remember
ever having to do this before. Why? If I have a clue I can code up and submit a patch.
If I recall correctly both my p2b and p2-99 boards do that while
running vendor firmware, though I don't recall ever seeing it while
running coreboot (which I just checked to verify it still doesn't show
up).
...
Back to how it failed to boot in the first place. The hard disk booting stalled after SeaBIOS. Took
me hours but eventually I found a line in my serial log that there has been a DMA timeout.
Turning UDMA off in devicetree.cb and flash again made it boot again. So I would have to revert
576315e1 (aka CB:40961), but I'm hesitant because that seemed like the reasonable thing to do
and it should have worked. So I'm also unsure why it didn't.
I've had the occasional issue with my p2-99 in the past, but I've
always got it booting again after reseating chips (flash/memory/cpu
card). I guess I should be making sure to have the serial link set up
more often, I normally only use it when I have a known bad version of
coreboot flashed. I actually have the cable connected between the two
boards right now, which seems to work decently for testing.
