I would not call optimize what I have found in my mailbox. That is a
hinf from Serguei Miridonov, to change the priority for the zorand
driver, it might help with your problem, but I'm really not soure. If
you computer lockes or doese something weird, please don't blame me.
Here is the description from Serguei:
> The latency timer is programmed by the BIOS first, according to configuration data
> and then can be changed by the driver. Old driver sets 32 for ZR36067 and 48 for
> ZR36057. It is possible to change this setting on the fly after the driver has
> been loaded. You will need setpci from PCI utilities to set the byte 0x0D in the
> ZR360X6 configuration space. Valid values are 0, 8, 16, 24, 32, ..., 240, 248.
> Since ZR36057 on the Buz card is beyond the bridge, it will appear on a different
> PCI bus number. Please, read lspci and setpci documentation for more information.
> Remember, every driver unload/reload will overwrite the latency timer again.
auf hoffentlich bald,
