Boot pauses for 2 minutes after upgrade to wily

[Tony Middleton]

Since upgrade to wily the boot process pauses for two minutes before continuing.

systemd-analyse shows

Startup finished in 16.356s (firmware) + 2.898s (loader) + 2min 46.836s (kernel) + 16.298s (userspace) = 3min 22.389s

CurrentDmesg.txt shows where the problem occurs.

The clocksource line is the last showing on the screen during the pause.

Maybe same as

however the tpm_tis.force=1 fix mentioned has no effect.

I will update BIOS as requested but I won't be able to do that for a couple of days.

In the meantime I must apologise as I haven't mentioned that there is another delay of about 40s as shown here

On the screen there are a number of messages about running scripts in /scripts the last one before the delay being
/scripts/init-bottom

Also, today I took out LVM temporarily and both of these problems went away and I booted in 18s. When I put LVM back the problems came back.

Managed to try updating after all. I tried both the F3 and F4 BIOS and both still had both of the delays mentioned above. Here is the output requested on the F3

sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
F3
02/05/2013

I'm currently on F3 but both F3 & F4 cause a new problem in that my USB keyboard/mouse isn't recognised during BIOS and GRUB. Had to borrow a PS/2 and if I can't find a solution will need to revert to F2.

[Tony Middleton (ximera)]

I recently removed an LVM snapshot that had been in place for some time. When I next rebooted the delay problem had gone away.

It seems this is a known problem. There are a number of bugs where root is on LVM and the delay causes boot to fail. I don't have root on LVM so boot did not fail but was unreasonably slow.
