The patch titled
libata: fix (hopefully) all the remaining problems with devices failing setup/identify
has been removed from the -mm tree. Its filename was
libata-fix-hopefully-all-the-remaining-problems-with.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: libata: fix (hopefully) all the remaining problems with devices failing setup/identify
From: Alan <alan@xxxxxxxxxxxxxxxxxxx>
Two fixes in this test patch. One of them allows old CF cards to refuse
pio mode setting, and one to wait for the drive to settle after a set
features changes the speed settings, which is based upon the workarounds
used by drivers/ide.
Please test and report back if you have an afflicted system. This patch
isn't for merging just testing.
The CF card fix will still display errors when the card works (got fixes
for that once I know the cure works) but should then be found/usable.
Not signed off by anyone, not for merging
