Most recent kernel where this bug did not occur: 184.108.40.206
Distribution: Debian unstable
Hardware Environment: Toshiba R100 laptop, see
Software Environment: Vanilla 220.127.116.11 from kernel.org
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 18.104.22.168

Please report whether (and how!) the IRQ assignments are different
between 22.214.171.124 and 126.96.36.199 ... 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 188.8.131.52. I will try later to boot with
the option you mentioned. and dig into the BIOS to play with the USB keyboard

"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.
