A user of the bas_gigaset driver reports that while his Logitech Laser Wireless mouse is connected to the system via USB, ISDN connections are regularly killed every 30 seconds by the clock. Debugging output from the driver shows that the two tasklets read_iso_tasklet and write_iso_tasklet handling the isochronous B channel send and receive data streams are simultaneously not run for an entire inter-packet interval, ie. 8 milliseconds. Disconnecting the mouse from USB and connecting it to the PS/2 mouse port instead makes the effect stop. Platform is Debian Lenny 64 bit, kernel 2.6.26, on a Gigabyte GA-EP45T-EXTREME Motherboard with an Intel Core Duo E8600 @ 3.3 GHz. Beside the Gigaset and mouse, there's a keyboard, printer and UPS connected via USB, but those don't seem to interfere. Applying a patch I have in my pipeline to schedule these two critical tasklets with tasklet_hi_schedule() did not help. Any idea what might be the cause of that problem and how to avoid it?
