Today I tried upgrading to 2.6.28-rc1-git1 (-rc1 couldn't even mount the disk). I'm having some problems with it :)
1) Whenever I try to unload (rmmod or modprobe -r) *any* modules (even if not used), the system hangs. I can still move the mouse and see the cursor moving, but I can't type, can't switch console, nothing. Because of this, I can't shutdown the system properly because it hangs when "Unloading ALSA modules"
If rmmod never returns, alt-sysrq-t output should show us where it got stuck.
Ok, done: http://marc.info/?l=linux-usb&m=122500580917403&w=22) Sometimes (randomly it seems) the system doesn't detect any usb devices: I have an external HD and a Logitech mouse. Sometimes they are recognized, sometimes not. Unplugging and re-plugging them doesn't help. lsusb shows no attached device.
Compiling with CONFIG_USB_DEBUG and sending report to linux-usb@xxxxxxxxxxxxxxx with the output included might be a good start.
