Re: [Bug 5808] aic7xxx - half speed/frequency

Could you keep the cc: list when replying, otherwise we lose the
tracking information in the bug database and on the list.

Could you try this again with 2.6.15, and then I can try giving you some
sysfs settings to prod to see if the driver can be forced up to 50ns.

Thanks,

James
