Uurgh.

Gabriel, can you please disable CONFIG_GOLDFISH and everything related to that?

Sure. I was about to start building the kernels.

I'll build an rc8 -CONFIG_GOLDFISH , -CONFIG_BLK_WBT + the debug patch from Linus.

An one with with reverted revert.. with same config then..


Ok some news .. without CONFIG_GOLDFISH && CONFIG_BLK_WBT + Linus debug patch + Mike's patch ,
+ 'x86/ioapic: Restore IO-APIC irq_chip retrigger callback' back in I have an working kernel.

Linus debug patch triggers once but that seems to be the netconsole.. ( e1000e stuff )

Now I need to find out which CONFIG_* option broke it ..

I'll start to re-enable *GOLDFISH things first since this seems to be somewhat broken.

Is the first thing I will do tomorrow.

Gabriel C
