Description Stefan Brandner 2006-01-24 19:45:16 UTC 
Hardware: Desktop AMD64 X2 4200+ in a ASUS A8N-SLI Premium
Software: SuSE 10.0 x86_64 with smb kernel

When I shut down my system all supplies despite the usb supply are turned off. After the shut down is complete my optical mouse which is connected to the usb bus is still lighting and e.g. the led of a connected usb stick is blinking.

If I try to start with the boot parameter acpi=off the system doesn't start.
So I need acpi to run the system.

With a knoppix cd the system shuts down correctly.

Please see http://bugzilla.kernel.org/show_bug.cgi?id=5276
which shows a series of steps to show if this is a kernel issue, or a
bios/hardware issue.

My bets are on the hardware/bios issue, as this is not something the 
kernel really controls.

If you follow the steps listed at the link above, and still think 
this is a kernel issue, please reopen this bug with the results of the tests.
