Perhaps you can find a testing software for the dual core cpu from your cpu or motherboard vendor Mitchell UBCD has numerous cpu testing programs on it, perhaps one of those? http://www.ultimatebootcd.com/ Adrian I have reconsidered the issue. I would approach your problem in a systematic way. You have some data. CPU seems to lock up with dual core set up. You find it with Debian install, but not with Windows. Bah I don't believe that. Yes it' s true, Windows runs on this machine with 2 cores without any lockups or bluescreens, but it's slower nevertheless ;-) BTW, ASUS hardware seems to be a bit strange anyway. They even built a limited Linux into the BIOS for faster startup (for surfing the net and such), but they didn't even manage to run it at the LCD's native resolution (which Debian does out of the box). If they have a console there I could look whether it recognizes the second core. Check using live CD: knoppix or finnix or some other ones. After booting try some tests. Make sure to do Mem86+ test for the ram and make sure your ram is good. Very often RAM is bad and can be confusing. you need to systematically test this stuff.

Thank you Mitchell. I will try these tests and report back, though it may take some time until I get to that.

Since I am not very accustomed with the kernel's compiling options, I used the old kernel's .config file. The problem stays the same with the new kernel. Normal boot -- freeze, boot with maxcpus=1 -- works, uname-a shows new kernel. Seems to be a general problem with this CPU. Or does anyone happen to have another idea for a solution?
