[root@amd-dinar-05 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.5 (Tikanga) [root@amd-dinar-05 ~]# cat /proc/cmdline ro root=/dev/VolGroup00/LogVol00 console=ttyS0,115200n81 noacpi pci=noacpi [root@amd-dinar-05 ~]# dmesg | grep bigsmp Overriding APIC driver with bigsmp [root@amd-dinar-05 ~]# cat /proc/cpuinfo | grep processor | wc -l 24 Seems to work on my system. What system are you using (vendor and model)? P. The machine should not boot without the fix for bug 622018. I don't believe noacpi is a valid kernel option. Can you try with acpi=off instead? Unlikely to be fixed for RHEL5. Closing as WONTFIX. P. |
