Re: [Xen-devel] [xen-unstable] Commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, makes dom0 boot process stall several times.

Hmm does seem to be a bit more random than i initially thought ... so that all 
seemed to be a red herring ..

Adding Andrew to CC Since i saw a thread about him working on a hpet interrupt 
issue ...


All this below was done running:
xen-unstable (git:ab7f9a7)
kernel: 3.9.0 (was using 3.11-rc's before, but downgraded to rule that out)

However ..  after fixing up my serial console i'm able to use the debug keys on 
the moment it stalls.
Pressing the key makes everything continue again, but nevertheless perhaps:

(XEN) [2066-12-22 10:22:58] Reboot in five seconds...






So i removed cpuidle and cpufreq=xen and tried "clocksource=pit" .. and now it 
doesn't stall anymore (both on boot and on reboot)  ...

So it seems when using the hpet broadcast it gets stuck in an idle loop ... and 
hitting a key on the console gets it out ...

I have attached a serial log from a boot with hpet as clocksource with some 
additional debug info.
While making this debug-key "V" to dump the interupt remap tables seemed to 
have another surprise resulting in:
