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

The kernel probably does it right (one space). But the kernel has to
communicate with udev which communicates with hal (transmission across
several spaces).

device_connect . udev_called . hald_reads_connect_from_socket .
hald_mounts_device ...

What if the device disconnects between hald receiving the connect
message and mounting the filesystem? Or, what if the device is mounted,
then disconnects and data is written to the device before hald receives
the disconnect message?

But, if you see this without hal, then my argument does become very

It's just that everytime I ran into "lost page write" or "buffer i/o
errors" it apparently had something to do with a mismatch between what
was perceived to be mounted and what was actually (not) mounted or vice
