dmesg when bug occured and usb stick was connected at boot
Description of problem:
If an usb stick is connected at boot it cannot be used/mounted, even if
re-inserted. There is no problem if the usb stick isn't connected at boot and is
inserted after. Also there is no problem with an USB mouse being connected at boot.
This problems happens 50% of the time.
It seems to be a irq problem, since Dmesg reports following:
hub 4-0:1.0: USB hub found
hub 4-0:1.0: 2 ports detected
irq 19: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #19
These lines, starting from "irq 19: nobody cared" are not present when there is
no problem with the USB device. If the problem occurs, the dmesg goes on to
report problems with accepting the usb devices:
usb 5-5: device not accepting address 4, error -110
usb 5-5: new high speed USB device using ehci_hcd and address 5
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot with an usb stick connected
the usb stick does not work (50% of the time)
the usb stick does work

dmesg when NO bug occured (and an usb stick was connected at boot)
So the issue is that when uchi_hcd probes its root hub, it manages to set off
an interrupt in the companion EHCI, which is not initialized yet at this time
(does not have a driver loaded). Perhaps BIOS has EHCI partially initialized
but not under its control, so at the moment of handoff we do not disable it.
Since we have a default handoff now, it may be feasible to try disabling
at the time. But it's difficult to cook something without having the
Would any additional information about the hardware be helpful?
