Technically the SMP kernel SHOULD boot on a machine with only one processor, but that's not always the case. If you're not sure if this box will become and SMP box, you can install both UP and SMP kernels on the box at the same time and for now set GRUB/LILO to default to the uniprocessor kernel and then if you ever add a processor, you can change the default boot option.
A Red Hat stock install will do this procedure by default on SMP boxes just in case there are problems, then you can boot the UP kernel to debug them. There is no harm in having both kernels installed unless you're low on disk space. Hope this helps, Andy. -----Original Message----- From: Carsten Gaebler [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 06, 2003 7:35 AM To: [EMAIL PROTECTED] Subject: Kernel 2.4.18 SMP hangs on Celeron at boot time Hi there, I have a single processor Celeron 1200 Machine which hangs at boot time when I compile the 2.4.18-24.7.x kernel with SMP support. Without SMP support it boots up fine. I have attached the boot messages. The "p" where it hangs is the start of the Unix98 pty driver message. Leaving that driver out doesn't solve the problem. The only error message that appears when booting with the "quiet" option is: Error: only one processor found. But this shouldn't be a problem because an SMP kernel should also run on a single processor machine, right? I need SMP support because i don't know in advance how many CPUs the machine will have. All 2.4.18 kernels from RedHat have this problem. I'd be grateful for some ideas. Maybe a BIOS issue?
