USB causing hang on boot/detection
The USB auto-detection is causing my system to hang while booting.
My system (detailed below) boots and works with the 2.6.10 kernel (though obviously missing a chipset I need which exists in newer kernels). Trying to boot to any of the following kernels fails (installed on a Mepis 3.3.1 dist):
2.6.11-? (The Mepis approved one)
2.6.12-3 (The one that can by found in these forums, normal and -k7 version)
2.6.12-3 (AMD64 compile from Debian repositories)
Specifying boot option "nousb" allows all of these kernels to boot fine (less usb support -- though everything else, including ATI chipset/sata drivers, works fine).
A new Debian boot fails for the same reason.
Disconnecting USB devices does not appear to help.
I am unable to get a dmesg log as the system does not boot with the failing kernels.
Any and all help would be much appreciated.
System:
Motherboard: MSI RS480M2 (disabling EHCI USB bus in BIOS does not avoid problem)
-AMD64 3000
