Patch to ahci.c

Although I bought Kuroutoshikou SATA3+USB3.0-PCIE (which have ASM1061 on), it had not been correctly recognized by kernel. It seems that it operates in AHCI mode although this card has a PCI IDE class (0x0101). 

Therefore, when I applied a patch to the driver, it is normally recognized by kernel and I could use it. 

For the moment, partitioning, data transfer, and getting S.M.A.R.T information, etc. are satisfactory.

I am sorry, this should have been reported to bugzilla of 3.2 brunch.
Comment 2 Alan 2012-05-12 02:16:28 UTC
Please see


in the kernel tree.

You should generate your patch with diff -u, add a Signed-off-by: line and send it to linux-ide@vger.kernel.org.

For various reasons we don't accept actual patches via Bugzilla

Thanks, and sorry it took a while to get to your bug report
