Re: JMicron Technology JMB362 JMB363 SError: { DevExch } ExpressCard, sometimes fails to boot

[Orson <orson.wellies@gmail.com>]

Hi,

Having received the replacement express card (197b:2363) I can confirm 
that the card in question appears to have been faulty.

The new express card performs flawlessly, I can cold boot / warm boot to 
Linux or windows without receiving any error message, and after several 
days of testing external disks I can honestly say that everything went 
without a hitch.

So, I would be happy if the bug report was closed with reason being due 
to faulty hardware.

regards

Orson
