All,
The attached patch should make CAM behave properly with regard to
probing device serial numbers only when the device advertises that
it supports it. It will hopefully eliminate the need for the
CAM_QUIRK_NOSERIAL quirk (one instance is left because of an unrelated
legacy problem that may or may not be possible to fix). This should
especially benefit USB-UMASS devices, where the console output should
be less noisy. It might even make more devices work out-of-the-box.
So please focus testing on USB, but I'd also ask that people test
the following devices as well as any firewire devices:
* Western Digital My Book 250GB (USB)
* Maxtor Personal Storage 3000XT (Firewire)
Good idea. I wonder, though, whether devices that hang or otherwise blow
up on a serial number inquiry would also have trouble with the supported
pages VPD page. All the more reason we'll need people with the quirked
hardware to test it...
