Will try.

I haven't seen any actual erros on the console, except these messages 
during bootup:

--------
pci0000:00: Requesting ACPI _OSC control (0x1d)
pci0000:00: ACPI _OSC request failed (AE_NOT_FOUND), returned control mask: 0x1d
ACPI _OSC control for PCIe not granted, disabling ASPM
--------

I have seen these messages in 3.2.0 (an Ubuntu kernel), can't say that I 
have seen them before, they did not show up when I booted this 2.6.38 
Ubuntu kernel.

I'll try booting with pcie_aspm=off and see what it gives...

Thanks,
Christian.

PS: AFAICT, Ubuntu's 2.6.38 [0] had these options set:

--------
CONFIG_PCIEASPM=y
# CONFIG_PCIEASPM_DEBUG is not set
--------

With 3.5.x, my .config has:

--------
CONFIG_PCIEASPM=y
# CONFIG_PCIEASPM_DEBUG is not set
CONFIG_PCIEASPM_DEFAULT=y
# CONFIG_PCIEASPM_POWERSAVE is not set
# CONFIG_PCIEASPM_PERFORMANCE is not set
--------
