Problem booting 2.6.24 with db800-Board

[Uwe Schwarz]

Hi,

I try to boot linux 2.6.24 with coreboot-v2 and filo on a db800 (geode  
lx) board, but it hangs when probing for PCI.

I tried to follow instructions on http://www.coreboot.org/Creating_Valid_IRQ_Tables 
  to find out my IRQ-Table.

Attached is a Capture of my boot.

With coreinfo as payload it boots up correct.

Maybe someone can point me in the right direction to solve this issue.

I think this is a known issue.

MFGPT timers on LX boards seem to not yet work correctly.

Try using another clocksource for the kernel and see if you can boot.

Thanks, that did the trick, my kernel is booting now.

Hmmm - no, this is badness.  2.4.24 and db800 should work fine in -v2.
At least, it worked fine last time I booted a few weeks ago.  We must
have regressed.

I found and fixed one issue(r3219) in the new (r3196) generic irq 
routing code back at the summit but it seems like there is still 
something wrong. Also, which VSA is getting built in?
