The pcie 06.0 bridge hang issue is the primary remaining issue. | |||
The Interrupt Mask Register (IMR) and Interrupt Service Register (ISR) are responsible for firing up different IRQs. The IMR bits line up with the ISR bits to work in sync. If an IMR bit is low, then the corresponding ISR bit with never fire an IRQ when the time comes for it to happen. The IMR is located at 0x3C and the ISR is located at 0x3E. | |||
Observe in the vendor bios pci configuration space dump attached below that, indx. 0x3C (IMR) = 0x0b and indx. 0x3E (ISR) = 0x01. | |||
IMR val. = 0000 1011 = INTB | |||
ISR val. = 0000 0001 | |||
