Description Sam Freed 2005-09-14 07:13:52 UTC 
Most recent kernel where this bug did not occur: 2.6.11.5
Distribution: Debian unstable
Hardware Environment: Toshiba R100 laptop, see
http://www.freed.net/opensource/R100.html
Software Environment: Vanilla 2.6.13.1 from kernel.org
Problem Description:
Geting the message "ehci_hcd 0000:00:1d.7: Unlink after no-IRQ?  Controller is
probably using the wrong IRQ" when trying to get at USB, following some bad PCI
stuff above, see dmesg.

Steps to reproduce:
Boot the machine into 2.6.13.1

Comment 5 David Brownell 2005-09-14 12:05:04 UTC 
Please report whether (and how!) the IRQ assignments are different
between 2.6.11.5 and 2.6.13.1 ... if they're different (like EHCI
not being on irq11) that suggests the issue is ACPI IRQ setup again.

Also, that "UHCI irq happens too early" thing seems likely to be
related to BIOS issues.  Try the "usb-handoff" kernel command line
parameter, and disabling USB keyboard/mouse support in the BIOS.

This is my first Kernel Bug, so bear with me --- I am attachning the
/var/log/messages and lspci -v from the 2.6.11.5. I will try later to boot with
the option you mentioned. and dig into the BIOS to play with the USB keyboard
stuff.

Comment 9 Sam Freed 2005-09-15 05:15:37 UTC 
"usb-handoff" worked. Oddly, it did not work as an "append=" in lilo.conf. I
suppose now it becomes a doc issue.

Ok, closing then.
