Package: linux-image-3.2.0-4-amd64
Version: 3.2.0
Severity: normal
Tags: patch
Please apply a backport of the JMicron USB->SATA quirk fix to 3.2.0 (wheezy).
Without this fix certain JMicron USB->SATA bridges are not usable in Debian
Wheezy.
The fix already is upstream (git b14bf2d0c0358140041d1c1805a674376964d0e0)
and in Debian's 3.16.0 kernel (Sid/Jessie).
A proposed backport of the fix is attached to this report.
