Hi! > Does anything use those two interrupts in an unbuffered state for UMB space?
NOT LBAcache, but TICKLE. The point is, only TICKLE has local buffers. So you should not load TICKLE to UMB if you have UMB DMA problems. LBAcache itself does not alter the buffer pointers - it just uses the buffers which the caller would have used anyway (usually the kernel, and the kernel has UMB-avoidance for buffers, as discussed earlier). Eric PS: I suggest to make vm86-DMA-trapping a command-line option. While it is true that you are faster without, un-trapped / un-fixed DMA can cause various system misbehaviour. If speed is not most important, I would still leave DMA I/O port trapping enabled on my system. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
