The system runs fine with RedHat 7.2 Linux (downloaded from hp website) with an 2.4 SMP kernel. However, running Gentoo with an SMP kernel will eventually make the system freeze (i.e make -j2 when building a new kernel only lasts for a 30 seconds or so). I've also tried NetBSD-5.1, FreeBSD-6.4, and a few other Linux distros with the 2.6 kernel (make -j2 makes the system freeze). It seems like Linux kernel 2.4 is the only OS that works with SMP on my system. Has anyone else experienced something similar with an UP2000+ Alpha system? First I suspected faulty hardware, but RedHat 7.2 seems to work just fine so... I heard somewhere that Linux going from 2.4 to 2.6 made some significant re-structuring of the SMP code that broke SMP support on some systems? The system has a Matrox Millenium and a 3Com 3c509B Ethernet card and a SCSI disk hooked up to the on-board SCSI. I've tried unplugging the NIC and a using a DEC PowerStorm 3D30 in stead of the Matrox Millenium, different CPU modules and different RAM modules. All with the same results. There are no error messages to be seen anywhere when the system freezes up. Regards Magnus --00151759312af5f2bc04a4ea51fe Content-Type: text/html; charset=ISO-8859-1 Hi,
