I've updated to linux 2.6.7 and applied the acpi patch for it. The behaviour is now a bit different. When trying to suspend (echo 3 > /proc/acpi/sleep) I now get the following: PM: Preparing system for suspend Stopping tasks: ===================================================================================================| PCI: Setting latency timer of device 0000:00:1d.7 to 64 Could not suspend device 0000:00:1d.7: error -5 ACPI: PCI interrupt 0000:00:1f.1[A] -> GSI 5 (level, low) -> IRQ 5 ACPI: PCI interrupt 0000:00:1f.5[B] -> GSI 10 (level, low) -> IRQ 10 PCI: Setting latency timer of device 0000:00:1f.5 to 64 Restarting tasks... done Device 0000:00:1d.7 is the USB 2 controller. If I remove the ECHI module the behaviour is as previously (i.e. locks up). I don't know if this is a new bug in the EHCI module or if this is the source of all the problems on this machine. I do not know enough of how things work at that level to determine if the USB controller could prevent the standby. The BIOS doesn't have an option to turn of USB so I can't try it with the hardware disabled. Any ideas?
