[Bug 35174] Re: ThinkPad X60 cannot resume from suspend to RAM

[James Henstridge]

Matthew: I tried the pci=nomsi option on my X60s using the 2.6.15-23.39
686 kernel.  That gives the following output in the dmesg output:

[4294667.296000] Kernel command line: root=/dev/sda3 ro quiet splash pci=nomsi
[4294667.296000] PCI: Unknown option `nomsi'

Later on in the dmesg output I see the following:

[4294668.285000] PCI: Setting latency timer of device 0000:00:1c.0 to 64
[4294668.285000] assign_interrupt_mode Found MSI capability
[4294668.285000] Allocate Port Service[pcie00]
[4294668.285000] Allocate Port Service[pcie02]
[4294668.285000] Allocate Port Service[pcie03]
[4294668.285000] ACPI: PCI Interrupt 0000:00:1c.1[B] -> GSI 21 (level, low) -> IRQ 177
...

It looks like MSI is still enabled with the kernel boot command line
option.  So MSI might still be the culprit for this bug.
