Hi,I started to experience random hangs of my laptop. Hardware info: Thinkpad x60s 1704-5UG also tested on a firends X60s 1702-F6U Kernel is 2.6.24 + these patches: tuxonice 3.0-rc5 thinkpad_acpi v0.19-20080107 tp_smapi 0.36 Sorry for the long delay, I'm just back from vocation. Some devices or chipsets don't work well with ASPM. This is one of the reason why the default policy of the patch is per BIOS setting. Ideally drivers should disable ASPM for specific devices, the patch provides an API (pci_disable_link_state) for this too. As Auke suggested, you can use the per-device interface to control separate links to see which device is broken. If you found one, please report to driver maintainer and me, we can disable ASPM in the driver.
