Hi Guys
It was suggested that I post on these mailing lists after I inquired 
about reporting ACPI related bugs in hardware to Dell, my problem is 
power management related issue with my Vostro 1310, using the tools 
provided by intel[1] I dump the asl using acpidump then try to recompile 
the asl to aml using iasl, which bombs out as there are too many errors:

Maximum error count (200) exceeded
vostro1310   225:     External (^CPU0._PPC)
Error    4014 -    From ACPI CA Subsystem ^  (AE_NOT_FOUND Failure from 
lookup %s

These bugs manifest as issues such as no battery status & sleep issues 
on FreeBSD which is annoying seeing as it's a laptop.

I have run acpidump & iasl on a poweredge 1950 & to show that there are 
bugs on server products aswell.
