0) For quite some time now, I see the following messages printed at each
boot, before plymouth's bootsplash takes over:
/proc/device-tree: can't find root
NMI watchdog disabled for cpu0: unable to create perf event: -95
ERROR: Unable to locate IOAPIC for GSI 13
ERROR: Unable to locate IOAPIC for GSI 8
ERROR: Unable to locate IOAPIC for GSI 1
ERROR: Unable to locate IOAPIC for GSI 12
ERROR: Unable to locate IOAPIC for GSI 6
ERROR: Unable to locate IOAPIC for GSI 4
ERROR: Unable to locate IOAPIC for GSI 7
ERROR: Unable to locate IOAPIC for GSI 3
(The device-tree message recently started showing up. I'd guess the
other messages are printed for at least a few months.)
1) I actually have no idea what these messages might mean, but since
I've been ignoring them all the time and this machine is still running
I'd say they could be downgraded to KERN_WARNING level. As far as I can
tell that should also keep everything quiet before plymouth starts.
2) This is sent to this list (and not to LKML) because:
- I'd like to see whether this list is useful for working on patches
before sending them to LKML;
- I might underestimate the severity of these messages; and
- these patches are untested! I've been entirely unable to rpmbuild a
kernel for i686 _only_, which just might keep the rpmbuild time at a
sane level. Does anyone know how to get Fedora's kernel.spec file to do
_only_ that?
