Well, yes, it's really slow to reach having a running ssh server. If I
let the machine boot, there's two reason in the log for the long time:

Jul 22 11:44:25.216867 Waiting for /dev to be fully populated...Timed out for 
waiting the udev queue being empty.
Jul 22 11:46:25.469002 done (timeout).

Jul 22 11:46:29.103350 Configuring network interfaces...
Jul 22 11:46:32.127350 ^@Timed out for waiting the udev queue being empty.
Jul 22 11:48:29.256918 [  403.298102] NET: Registered PF_INET6 protocol family
... more network kernel info after that.
Jul 22 11:48:33.204921 Waiting for xenbr0 to get ready (MAXWAIT is 2 seconds).
Jul 22 11:48:33.204984 done.

(on previous run, "configuring network interface" is followed by
"waiting for xenbr0")


So, we lost already 4 min waiting, out of a budget of 7min for full
reboot.

Also, "reboot" doesn't work with this newer kernel, the machine prints
"Will now restart." then nothing happen.

I have also try without Xen, it's the same behavior.

Cheers,
