[Bug 88746] Re: ehci_hcd module causes I/O errors in USB 2.0 devices

[b]

Ok, so It looks like this is the problem I'm also having.

I have two questions:

1. I cannot yet confirm this bug because I've not unloaded the ehci_hcd
module. This is because my usb drive is still connected. I umounted it
with -l, and I'm still seeing I/O errors in the syslog. fuser and lsof
show me there are no processes that are still running on the device.

Is there anyway I can force the kernel to just stop trying to write to
the disk? Last time I rebooted in this state the shutdown scripts halted
on these same errors, and I had to hard reset anyhow. Do I have any
other options that just waiting until the I/O errors stop when it gets
to the end of the disk? I've caused enough filesystem damage on this
machine due to this bug, and would like to stop doing it.

2. can ehci_hcd be added to the kernel module blacklist so its not
loaded on bootup?

Thanks,
B. Bogart
