EHCI controllers that don't cache enough microframes can get MMF errors when CPU frequency changes occur between the start and completion of split interrupt transactions, due to delays in reading main memory (caused by CPU cache snoop delays).
This patch adds a cpufreq notifier to the EHCI driver that will inactivate split interrupt transactions during frequency transitions. It was tested on Intel ICH7 and Serverworks/Broadcom HT1000 EHCI controllers. Signed-off-by: Stuart Hayes <[EMAIL PROTECTED]>
