Hi all I am using the "Red Hat Enterprise Linux ES release 4 (Nahant Update 1)" kernel 2.6.9-11.ELsmp in the machine 2 x AMD Dual Core AMD Opteron(tm) Processor 275 When we reboot machine, sometimes it is hanging on "Enabling swap space" after reset, booting is successful. but got an error message /etc/rc3.d/S00microcode_ctl: microcode device /dev/cpu/microcode doesn't exist? do you know what is the exacting problem? Can we diable microcode? Thank you -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
