GX2 problems

[Nils]

Hi all,
Attached patches add the Wyse S50 thin client to Coreboot.
I have rev5446  and some older rev`s working here with different hacks but 
rev5484 and 5520 (and some i tested in between) are not working anymore.

Linux gives the following error: "hda: lost interrupt" .
Attached also the bootlogs from rev5446 and rev5520.

Could somebody give me a hint (or even better a patch) i can try?

Although the patches are probably not ready for inclusion:

Signed-off-by: Nils Jacobs

Thanks,Nils.

Hey Nils,
I just acquired as S30, which is the same as the S50 but less onboard 
flash/memory :-)

Very nice!
The more people working on it the better.
I hope the GX2 tree is working again soon.

P.s. i forgot to mention there is another problem that i always had:
Stage:loading fallback/coreboot_ram takes very long to load .(~35seconds)

Thanks,Nils.

Quick question, is the onboard flash detected as IDE device or as MTD 
device?

The standard BIOS is configured for Flash not IDE.
I didn`t use the flash yet.
I have a 2,5` laptop hdd attached to it on the intern power supply
and that works ok.
After long experimenting i found a kernel config that seems to work
only on kernel 2.6.24 and enables the hdd on the flash interface.
Probably a bug in 2.6.24.
I use that kernel for flashing.
If you need that give me a pm.

Greetings,Nils.

What's this doing?

Is it potentially dangerous for other systems?

Hi Stefan,
I specifically tested this again on my patched rev5470 (the last working 
version here) and it is needed there.
Without it Seabios refuses to work and coreboot reboots.
I don`t know what it does on current trunk because  it never gets til Seabios.

I don`t think it is dangrous to other systems because the GX2 tree is broken 
for more than a year and probably never worked with Seabios.

It would be nice if you could commit it.

Thanks,Nils.
