Hi Rafael,
I will send out a patch today for this issue. On Thomas
Voegtle's system, the issue is caused by that BIOS report incorrect
length for ACPI address space descriptor. For example,
[ 0.761553] acpi: address space [80000000-d0716ffe] len 50717000
[ 0.767572] ACPI: invalid or unassigned resource mem
[0000000080000000 - 00000000d0716ffe] length [0000000050717000]
BIOS should report length of 0x50716fff instead of 0x50717000.
So seems we need to relax the length check code to workaround
such bios issues.
Will send out a patch for it soon.
Thanks!
Gerry
