Comment 8 for bug 144210

PCMCIA USB ports was messing up everything, but got it also worked around. Final fix to have everything except onboard USB 1.0 ports in Dock working:

1. In BIOS Config->PCI, all INT should be set to auto

2. /etc/initramfs-tools/modules should contain:

fbcon
thinkpad_acpi
dock
thinkpad
pcmcia
uhci_hcd
ohci_hcd
yenta_socket

3. kernel options: irqpoll (optional acpi=off can be used to run USB 1.0 port)

Results of the above settings:
- PCMCIA Card with 2xUSB 2.0 & 1xFirewire plugged in Dock PCMCIA slot works fine
- Winfast Leadtek 2000 XP plugged in Dock PCI slot works fine
- Mouse plugged in USB 2.0 on PCMCIA card works fine
- USB#1 in Dock is not working even using acpi=off
- USB#2 in Dock works fine when acpi=off parameter is set in kernel

Conclusion: modules mentioned above should be passed to initramfs by default after Ubuntu installation, also some diagnostics should be made to check why both - ACPI and Dock USB support can work at the same time.

Since Dock is usable as I wanted it to be, I'm done with this.
