Freeze during boot on core2 quad E6600

Description

Haiku freezes during boot on a core2 quad E6600 (at 2,4GHz) shortly after MTRR initialization. Entering KDL is not possible (PS/2 and USB keyboard)

When disabling SMP it boots, tested with hrev32769. (entering KDL also works)

The last version tested that didn't freeze (even overclocked at 3.0 GHz) was hrev30474.

I can reproduce the same on my Q6600. This is a recent regression, as hrev32438 still worked fine. I have removed ATA to see if it was caused by the switch, but it didn't make a difference (booting from SATA over AHCI, so don't really need ATA). I'd say that's a critical regression. Will binary search to find the problem.

I've the same feeling here, some change(s) in last 2 weeks make SMP unstable, as the issue doesn't show without real support for actual parallelism.

I'm binary searching the issue. Last working hrev32739, building hrev32760 now. Will find it eventually.

I didn't find the time yet to bisect that issue, but I verified that hrev30700 with ata patch from hrev32769 applied does boot just fine in SMP mode, using the ata stack.

hrev32500 works, too
