if you don't want to penalize all JMicron models then a workaround would
be to create a new feature : the ability for the user to disable async
for a specific device,

for example a kernel parameter ( no-async-for-jmicron ), or a more
configurable mechanism, like a configuration file where the user can add
the name of the device, a kind of blacklist in order to disable async
only for a list of devices,

it's only a workaround, the real solution would to be find the real root
cause ( a bug in async method ? a design flaw in JMicron hardware ? a
bios/acpi bug ? )
