I will include the change into our new= driver version and will send a patch for 2.6.4 on Monday next week to Linu= s. >=20 I dont think this patch will be sufficient - There is another problem with the driver - What for example happens if we are in the gdth_interrupt - we do have locked the HA because we are not in polling mode. Then the error handler kicks in and sets polling_mode to TRUE - Now the gdth_interrupt will not unlock the HA which will get one cpu to keep spinning in the error handler. I think calling the gdth_interrupt in polling and non-polling mode is bogus by design.
