Originally this was disabled to work around RHBZ#502058. That bug was
never officially fixed, but it may have fixed itself.
In the meantime, KVM has broken ordinary PIC support (RHBZ#723822).
Since APIC is the most common way that regular Linux and Windows
guests run it makes sense to remove this hack.
"panic=1 " /* force kernel to panic if daemon exits */ \
"console=ttyS0 " /* serial console */ \
"udevtimeout=300 " /* good for very slow systems (RHBZ#480319) */ \
- "noapic " /* workaround for RHBZ#502058 - ok if not SMP */ \
"acpi=off " /* we don't need ACPI, turn it off */ \
"printk.time=1 " /* display timestamp before kernel messages */ \
"cgroup_disable=memory " /* saves us about 5 MB of RAM */
