Comment 574 for bug 88746

So, if I run:

dmesg | grep ehci*

I get:

But if I run:

modprobe -r ehci_hcd

I get:

FATAL: Module ehci_hcd not found.

Is my kernel (2.6.31-17) haunted by the ghost of this THREE YEAR OLD bug?

Also, changing 'scheduler' doesn't help. Changing 'max_sectors' doesn't help.
