I'm getting a hang near the end of booting on x86_64 UP.
The last initcall_debug function varies. E.g.:

So perhaps it locks during a timer interrupt.
.config is attached.
Any ideas/suggestions?
Just the usual: nothing from sysrq or NMI watchdog?
Nothing from either of those. I'll jiggle some config options.
config option changes didn't help, but removing
netconsole=<params>
from the kernel command line makes it all happy. :(
argh.
Do we know of netconsole hang problems? (anyone?)
You have "time" as well? I found on i386 uniproc that time+netconsole
caused hangs because the printk timestamping code was taking
xtime_lock for reading inside a write_seqlock. But I though that Andi
fixed that. Perhaps i386 got fixed but x86_64 did not.
Yes, I have CONFIG_PRINTK_TIME=y and disabling it allows it to boot. Thanks.
Maybe the patch isn't merged yet?
Now if I can just remember this until the next time that I hit it...
