2.6.17-rc5-mm1 promise_sata bugs

[Sascha Warner <_@i12.com>]

I recently compiled 2.6.17-rc5-mm1 and it BUGs me while initializing my 
promise TX2 Plus SATA Controller. Here is the message (handwritten, but 
double-checked):

<0>Kernel panic - not syncing: Attempted to kill init!


This happened some mm kernels before (since libata update I guess)

Just ask for any information you might need.
Is there anything you want me to test?


kind regards
