I just got again a chance to boot up my b160L and 715/64 machines.
Both broke due to the IRQ changes. I did reverted all of your IRQ
patches (based on current Linus head branch) and now they boot
again.
Basically they just hang during the SCSI initialization (timeouts
while detectings discs).
So, there is something wrong for Lasi/GSC and Dino busses....
Any idea?
No, but I'll take a look, it's probably something simple and stupid that
I missed. :/
I tried to look into it, but I'm somewhat lost.
This is what I get on my B160L.
Same result btw on the 715/64.
