Risking my mostly worthless IDE drive I Could you get a copy of lsprop (ftp://samba.anu.edu.au/pub/linux-pmac/misc) and do `lsprop /proc/device-tree/bandit/ohare/ide' (or whatever the node for your IDE controller is called) and send it to me? In fact we don't use the DMA interrupt, so the test for np->n_intrs could be removed. Paul. [[ This message was sent via the linuxppc-dev mailing list.
