having usb modules loaded may cause failure to resume from disk

[Emilio Scalise]

By default uhci_hcd, ehci_hcd and ohci_hcd are loaded in initramfs on boot, also when the system has to be resumed from suspend to disk (swsusp1).
This cause a failure on usb wakeup on my machines (an acer 2012wlmi laptop and a desktop computer, P5ND2-SLI (nforce 4 intel edition) with a P4).

If I set mkinitramfs to load only the list of strictly necessary modules usb will survive after resume (it handles well wakeup).

I know that usb modules can't be easily removed from an initrd as someone could boot from usb disks... but what you think about adding an option to select to not include them? Or at least document this behaviour.....

Can you describe the failure? What does dmesg look like?

You can find another user that have the same problem...

It's the same error I have fixed........

Thank you for your bug report. Do you still have this issue with the latest release of Ubuntu ?

[Emilio Scalise (emisca)]

Unfortunately I have sold that notebook last month. Perhaps I tried with edgy's 2.6.17 kernel, and the behaviour was the same.
We could ask on laptop mailing list if someone has a similar acer notebook..

Bye...

Well, I will close this, if someone still has this issue, feel free to reopen.
