https://community.hpe.com/t5/operating-system-linux/16-core-dl580g5-with-ubuntu/m-p/4420739#M61441 I've installed Ubuntu server 8.04 and have all of my RAM and 8 of my CPUs visible as expected. I've rebuilt the kernel to support 16 CPUs, but when I boot, I get as far as "Brought Up 16 CPUs" and then the system hangs. If I turn off half of the cores in the BIOS the system boots fine.<BR />I'm fairly certain the kernel build is good, so I'm not sure what's causing the problems. Anyone seen a similar problem on another linux distro, or got Ubuntu working? The kernel I'm using is 2.6.24.<BR />I've tried the usual args on boot to disable ACPI etc with no success. The BIOS appears to be the latest, dated 23/09/08.<BR /> Fri, 15 May 2009 09:04:27 GMT Jim Hayden 2009-05-15T09:04:27Z https://community.hpe.com/t5/operating-system-linux/16-core-dl580g5-with-ubuntu/m-p/4420739#M61441 I've installed Ubuntu server 8.04 and have all of my RAM and 8 of my CPUs visible as expected.
