Using port80.c, I could hard lock a HP Pavilion tx1000 laptop on the first go. This was with ubuntu hardy's stock kernel (a 2.6.24-rc) > dmidecode -s baseboard-manufacturer > dmidecode -s baseboard-product-name Quanta 30BF Tonight, I will try compiling a kernel with these values added to your patch. Some history, feel free to ignore if it's not relevant: ubuntu feisty's 2.6.22 based kernel worked fine, irc. We were having issues with sound, so tried fedora8's .23 based kernel, but this would sporadically hard lock. Ubuntu hardy's 2.6.24 appeared fine, for the 2 hours or so I used it last night, until using the port80.c program, obviously.
