oops on boot from Jmicron patch

[nick materer]

Binary package hint: linux-source-2.6.17

oops on boot with linux-image-2.6.17-generic on a P5B board. No oops when Jmicron is disabled with the bios.

Problem is that not all the patch was applied due to a problem applying the 2.7.18 patch by the kernel mantainors

+ [PATCH] PATCH: 2.6.18 oops on boot fix for IDE
+
+ When the IDE fix for Jmicron went in one piece went walking somewhere
+ (send log shows my end somehow). Without this sometimes you get an oops
+ on boot.
+

Adding the additional patch (see below) to the ubuntu 2.6.17 source fixes this problem

I've cherry-picked this patch. JMicron was gracious enough to send me an
eval board last week. It should be arriving today. Once I test this
patch (no more blind patching and hoping things work), and get ich8
working, I'll do an upload (hopefully later this evening).

Kernel will be available in a few days.

linux-image-2.6.17-generic works on my P5B board with no oops at boot!

Thanks
