I'm not sure if I have enough of the right kind of DIMM sticks to populate my 7500WV2 motherboard to 4GB, so would you mind doing some tests for me? If the aac driver is compiled into the kernel, add the line 'options aac_DEBUG' to teh config file and rebuild. You'll also have to edit /sys/conf/files and remove the '#' at the beginning of the line that contains 'aac_debug.c'. If you load it as a module, then edit /sys/modules/aac/Makefile and remove the '#' before the two lines at the bottom that are marked as being for debugging purposes. Once you have debugging enabled, send me a console log that shows your complete dmesg and the output given when commands start timing out. Thanks!
