Description Bruce Duncan 2007-12-29 17:11:38 UTC

Most recent kernel where this bug did not occur: 2.6.18

Something changed in i8042_check_aux which meant that my synaptics touchpad was no longer detected because it doesn't reply to the loop command. There is an entry for it in the dmi noloop table in i8042-x86ia64io.h but the whole thing is enclosed in an ifdef __i386__. The same problem happens on x86-64 so I wrote and tested a patch to enable the dmi check on 64-bit as well.
