[PATCH RESEND] (revised) Calgary: increase max PHB number
There was a small difference in 35-rc3 that prevented this patch from applying, so I regenerated it. =============================== Newer systems (x3950M2) can have 48 PHBs per chassis and 8 chassis, so bump the limits up and provide an explanation of the requirements for each class.

[PATCH] x86/mrst/pci: avoid enabling intx for msi capable devices
On Moorestown platform, true PCI devices with MSI capabilities do not support INTx mode. IRQ line# for those devices are zeros in the PCI shim, an attempt to enable INTx on these MSI capable devices will cause conflict in the system such as IRQ0 for the system timers. If the device driver probes/enables MSI before ... 21 Jun 2010 14:40

Circa 2007 there was talk of a patch to replace the underlying msleep Implementation with hrtimers ( http://lkml.org/lkml/2007/8/3/250 ); this ended up not happening for several reasons, but the idea of a usleep call built on hrtimers was at one point tossed around in the discussion. However, it seems that usleep i... 21 Jun 2010 14:40

In one case processes wer waiting in sk_wait?? or so and one sees libfakeroot: read: Connection timed out after awhile. Wereupon the build continues for a while until it hangs for good.
