[Bug 592780] Re: [Lucid] kernel suspend + resume works only once, 2nd timesystem freezes

[ingo]

Here the result:

with a PS/2 mouse attached and kernel parameter "nousb" all is fine. I
can suspend + resume as much as I like!

The same (PS/2 mouse), without "nousb" but no USB-devices attached, it
only works 1x and hangs on 2nd suspend.

With Hardy I did unload ohci-hcd module, which is no longer possible in
Lucid, as it is compiled into the kernel. And the worst, not only ohci-
hcd, but also uhci-hcd and ehci-hcd. This is absolutely wrong, as IMHO
there is no hardware which needs OHCI and UHCI at the same time -
either, or should be used!

So, with current kernel configuration we are lost on our (quite widely
spread) hardware, unless Canonical compiles kernel with USB configured
as modules, so we can unload them before or unless they provide proper
initialisation scripts :-(

CONFIG_USB=m
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_OHCI_HCD=m
CONFIG_USB_UHCI_HCD=m
