It didn't work for me that way. It still works for me to use the reset button.
Hrmm. That's weird. Can you send a SeaBIOS log of a run where you boot up until failure, press ctrl+alt+delete, and then go to the failure again?
Sure. From what I've been able to tell, there's nothing significant there. SeaBIOS detects the drives the second time
Oh - I was only looking to see if SeaBIOS could detect the drives the second time. Can you see if the patch below fixes the problem for you?
, but when Linux tries to boot it gets confused when it tries to load the SATA drivers and hangs. I don't think I was clear on that before. It could be related to the interrupt routing problems, or something that's not getting reset correctly by Coreboot.
On ctrl+alt+delete, coreboot isn't called. I've seen problems with SeaBIOS booting after a soft-reboot, but I don't know why. It looks like SeaBIOS is doing a full internal reset correctly..
If you send the full log, maybe it will help diagnose that problem.
