Hi all,
So with the previous patch to change the initial timer values applied to SVN trunk, we now get much further on a Solaris 8 boot:

From Artyom's OBP output, we can see that the next few lines that should appear on the console look like this:
sd2 at esp0: target 2 lun 0 sd2 is /iommu at 0,10000000/sbus at 0,10001000/espdma at 5,8400000/esp at 5,8800000/sd at 2,0 root on /iommu at 0,10000000/sbus at 0,10001000/espdma at 5,8400000/esp at 5,8800000/sd at 2,0:b
Therefore the crash is being caused by Solaris either trying to access the esp device or doing some kind of enumeration on the ESP bus.
ESP 'reg' property is not correct: reg: 00000005.08800000.00000040
reg 00000005 08800000 00000010
Could that cause the fault?
