Subject: Regression between 2.6.20 and 2.6.21-rc1: NCQ problem with ahci and Hitachi drive
Date: Mon, 05 Mar 2007 01:51:12 +0100 [thread overview]
Message-ID: <45EB6980.90600@crans.org> (raw)
Hello,
I have and laptop with an ICH6M SATA Controller and an Hitachi hard drive.
While it worked well using the ahci module and with NCQ enabled using
Linux 2.6.20, it does not work anymore (hang at boot) with 2.6.21-rc*
My drive is among those that were recently blacklisted (see lkml post
"[PATCH] libata:
add NCQ blacklist entries from Silicon Image Windowsdriver)
(Model Number: HTS541010G9SA00 and Firmware Revision: MBZOC60D)
This blacklisting patch is in -mm now.
So there is probably a drive related issue here, I'm just wondering why
it just work
flawlessly with a 2.6.20...
