If you thought it might help I'd probably be willing to hang upside down from the doorframe. > The attached patch, against kernel 2.6.5, updates libata to the code > that is found in kernel 2.6.6. Yep, see the attached dmesg.. problem followed the libata code :p( All I did was a cp -av on my 2.6.5 tree, applied your patch, added a -testbk to the Makefile, did a make oldconfig && make && make modules_install && reboot Hangs for a while at the end and then spits out a dma timeout, never to recover. my grub entry was a direct copy of the 2.6.5 one with -test added to it.
