on the down side I am still experiencing the odd random hang
After power off/power on or after reset?
I mostly notice it after a power on as I usually power off after reflashing the ROM. Once it hangs a reset will sometimes start it. Other times I can sit there reseting it for quite a few attempts without luck, at which point I usually reboot with the original BIOS.
From the output it appears to be sticking in ram initialisation, possibly reading the SPD info, however all of the SMBus functions appear to have timeouts so I don't think it should hang, unless they are not working properly. Of course the hang may just be coincidental with the SPD stuff and have nothing at all to do with it.
Did disabling UART interrupts eliminate the hangs?
It didn't appear to. I did still get some hangs. Often just changing a single line of code may make things better or worse, however the hang always seems to happen at 1 of 2 points.
Does ROMCC warn if it runs out of registers ?
and power off still does not work with ACPI only compiled into the kernel.
Which board do you have again?
I have the standard EPIA vt8601 NB, vt8623 SB.
Can you compare ACPI tables between factory BIOS and LinuxBIOS?
How do I go about getting that info ?
