If you need to protect your pseudodriver from being interrupted by the real driver then you'll need to use the same spl() as the driver. Note that you shouldn't be using splhigh() unless you really know what you
the driver currently is set to use INTR_TYPE_MISC, which from my understanding can only be masked with splhigh(). using another INTR_TYPE may be possible, so this is something i can explore.
however, the device interrupts at a constant 1000Hz, as it's a quad-span E1/T1 line card, and thus it needs to have that interrupt serviced pronto to avoid E1/T1 frame slips. any advice here ?
