Upgraded to Kubuntu Feisty Fawn 7.04, kernel 2.6.20-13 installed. pam_bioapi was working fine under 2.6.17-11, but immediately after upgrade, I am experiencing USB problems. Attempting to login, the pam module causes the following to be printed to stdout:
[ 357.656000] hub 1-2.3:1.0: hub_port_status failed (err = -71)
[ 357.656000] hub 1-2.3:1.0: cannot disable port 1 (err = -71)
[ 357.660000] hub 1-2.3:1.0: hub_port_status failed (err = -71)
[ 357.768000] hub 1-2:1.0: port 3 disabled by hub (EMI?), re-enabling...
This works very occasionally (not the first time I tried it either, somewhere around the 20-30th time that the module was used) and not consistently. Other than that, the machine consistently prints that error and falls back to password auth every time.
The only special boot options I have tried are pci=assign-busses and pci=routeirq as dmesg recommends them:
Apr 3 18:19:43 novosirj-laptop kernel: [ 0.205402] PCI: Bus #04 (-#07) is hidden behind transparent bridge #03 (-#04) (try 'pci=assi
gn-busses')
Apr 3 18:19:43 novosirj-laptop kernel: [ 0.205404] Please report the result to linux-kernel to fix this permanently
...but this has apparently no effect, except appeared to make things slightly worse. A recompile of the module also had no effect.
Another bit of information is that this DOES continue to work if I boot back into the still-installed linux-image-
Please advise me if I may need to provide more information.

Still behaves the same in 2.6.20-14.
