Subject: [PATCH] mb/dell/e6400/acpi: Route Ricoh R5C847 PCI IRQ lines as DBC
|
||||
|
||||
Based on the schematic and vendor ASL code, PCI interrupt lines ABC of
|
||||
the Ricoh R5C847 PC Card/Media Card/FireWire controller are routed DBC.
|
||||
From lspci and the schematic this chip is PCI device 1. The original
|
||||
config copied from the T400 was routed ABCD->BCDA, causing Linux to
|
||||
issue an "irq 18: nobody cared" message when inserting an SD card.
|
||||
This is fixed by this patch and the SD card now works properly.

||||
