<enter> ???
udev does not read from the keyboard :)

try "udev.loglevel=info" on the kernel command line
Comment 2 sean 2010-10-31 10:13:40 EDT
Well forever was wrong. If I don't press a key, it's almost exactly 5 minutes:

[    4.447693] dracut: Switching root
[    5.162934] readahead: starting
[    6.473625] udev[463]: starting version 161
[  306.621264] Clocksource tsc unstable (delta = 300006081409 ns)
[  306.631726] Switching to clocksource hpet
[  309.016668] type=1400 audit(1288493951.141:4): avc:  denied  { mmap_zero } for  pid=483 comm="vbetool" scontext=system_u:system_r:vbetool_t:s0-s0:c0.c1023 tcontext=system_u:system_r:vbetool_t:s0-s0:c0.c1023 tclass=memprotect
[  309.308590] microcode: CPU0: patch_level=0x10000bf
[  309.620698] EDAC MC: Ver: 2.1.0 Oct 19 2010

I had "udev.loglevel=info" on the kernel command line, but I don't see anything else in syslog.

If not udev, is it clocksource? Whatever it is, it makes F14 unworkable on a server.
