Re: What breaks aic7xxx in post 2.6.12-rc2 ?

[Dinakar Guniguntala <dino@in.ibm.com>]

Here's a me too report. 

This is controller that I have

00:0e.0 SCSI storage controller: Adaptec AIC-7896U2/7897U2

I never used to get warning such as "refuses WIDE negotiation"
in kernels prior to 2.6.12-rc3-mm3.
The machine (x86) boots up fine though.

Here's the relevant dmesg output from 2.6.12-rc4-mm1
