Hi David,

If the device is rapidly connecting and disconnecting in a way that
isn't contained by the USB subsystem, isn't that going to cause problems
for the block device driver and, consequently, the filesystem driver?
If you have problems in kernel space, who cares if hal is confused?
Aren't things going to head south anyway?

Anyway, I've seen this issue many times running in nothing more than an
initramfs environment, without hal.

I don't believe it's accurate to say that "Kernel developers apparently
don't believe it has anything to do with the kernel".  The kernel bug
report that is linked to appears like it may have actually been caused
by defective hardware in that particular case.  We're probably not
seeing a good response from kernel developers because we are trying to
piggy-back real bugs on top of a report caused by a hardware defect.
We're just not communicating with kernel developers well.
