I have a fresh install of UNR 9.10 on my Dell Mini 9 (with the Super Talent 16 GB SSD), and I am suffering from painfully slow boot times. Right now, it is hovering at around 100s to boot to the desktop, and according to the bootchart, it is simply idling for around half of that time or more. Does anyone know how I can fix this?

From what I can see, it idles for around 30s in the beginning, possibly waiting for some hardware detection step. It also idles for around 30s after I login before it loads the desktop. Please let me know if you have any ideas! Thanks.

Does it seem to run correctly once up? Can you suspend and resume quickly? Suspending instead of shutting down might be a workaround. Thanks to suspend/resume, my Mini 9 hasn't been truly booted in over a month.


As for actually identifing the problem:

Network issues are my #1 suspect, especially 'cause googling "udev slow boot" brings up a link referring to slow boots with a Broadcom WiFi driver.

Blacklist the WiFi driver and see if boot times improve (although obviously, you'll lack wireless ).

Same problem here - I took out the Super Talent (2 minutes plus for boot time) and put back in the STEC 4GB that it came with and the boot time is normal (42 seconds from turn on to usable desktop).

There's a long string of posts in this bug report regarding this:

I have the same issue with 9.10 and thought it was just annoyance, but from that bug report it sounds like the issue can potentially brick an SSD. Yikes.

I tried the workaround posted in post #114 of the bug report:

https://bugs.launchpad.net/ubuntu/+s...2?comments=all

and my boot time went from over two minutes to 32 seconds - Faster than Jaunty, faster than with the factory installed STEC 4GB SSD. Everything seems to run fine.

Mini 9, Super Talent FEM16GFDL, Ubuntu 9.10 lpia.

Mizar, I will try your workaround, as I just upgraded to a Sabertooth/Super talent ssd and I don't want to just blame the hardware for my long boot times.

WORK AROUND FOR THIS PROBLEM: IT WORKS! Using a super talent/sabertooth 32gb ssd. Nice, snappy boot time!

1. sudo gedit /lib/udev/rules.d/95-devkit-disks.rules

2. locate the following lines (about 1/3 the way into the file; search for "smart")

# ATA disks driven by libata
KERNEL=="sd*[!0-9]", ATTR{removable}=="0", ENV{ID_BUS}=="ata", ENV{DEVTYPE}=="disk", IMPORT{program}="devkit-disks-probe-ata-smart $tempnode"

3. comment out the second line by adding a # in front, so you should have

# ATA disks driven by libata
#KERNEL=="sd*[!0-9]", ATTR{removable}=="0", ENV{ID_BUS}=="ata", ENV{DEVTYPE}=="disk", IMPORT{program}="devkit-disks-probe-ata-smart $tempnode"

4. save the file and reboot

I reverted back to 9.04 after zeroing my SSD. While the workaround works, special care needs to be taken to keep updates from undoing the custom code. That's too much of a pain in the butt for me. I think I'll wait til 10.04.

Lurv,

I just installed updates for Ubuntu, and now my mini doesn't want to boot - I have to fix it in root! So, yeah, fun times!

The workaround for this thread's bug just got committed and is available if you update.
