ACSIM: DF-2372 raw pci_cfgregread(0:0.0, reg0, 4 bytes) = 0x12378086
ACSIM: DF-2372 AcpiOsReadPciConfiguration Width=32 -> status 0x0 value 0x0000000012378086
ACSIM: DF-2372 AcpiOsReadPciConfiguration Width=16 -> status 0x0 value 0x0000000000008086
ACSIM: DF-2372 VERDICT: 32-bit read returned the real value (mask did not zero it) - NOT reproduced on this compiler.
(fix validated: Width=32 now returns the real 0x12378086)
