Hi

I am running Ubuntu 7.10 on a Lenovo X61s.  very nice I have to say.

When I run suspend (to RAM), when the machine comes back up, everything
else works (usually) except USB. I have tried restarting the dbus
daemon, unloading and reloading uhci_hcd and ehci_hcd. 

note that *all* my USB ports are dead - I havce seen posts where the RHS
ones only are dead after resume. 

A complete reboot rings everyuthing up as normal.

I have the acpi_sleep=s3_bios in my kernel at boot, as that fixed
problems I was having with the ipw3945 wifi card. 

I have also set the PCI IRQ to Auto in the BIOS (made no difference).

Any help appreciated!

If you need more information, just ask.

Pete
