Ubuntu Server 14.04 64bit on DELL 1950

Asked by luciano rinetti

I use the install CD to prepare my DELL 1950 equipped wit 8GB of memory and two 600GB HD in RAID1 managed by a PERC 5/i RAID controller. The BIOS was 2.7.0 (last available from DELL) and the PERC FW is updated too. All the install process was successful, so i reboot the system. The first time the boot was ok but as soon i reboot again, the system get stuck with these last messages on the console:
...
random: nonblocking pool is initialized
init: plymouth-upstart-bridge main process (232) terminated with status 1
init: plymouth-upstart-bridge main process ended, respawning
init: unreadahead main process (235) terminated with status 5
Adding 15625212k swap on /dev/sda3. Priority:-1 extents:1 across:15625212k FS

after that i need to power-cycle the system. This problem is not systematic, but 50% reboot get stuck in this way.
Given that i gave a second DELL 1950 in the lab (with the same HW), i repeated all the install process in the same way, and i get the same problem again. I manually partitioning with XFS the disk during the install: 512MB in the boot partition, 30GB in the root partition, 16GB swap partition and roughly 550GB on the var partition (all the remaining left space).
Can you help me to debug ?

Have you tested your RAM using Memtest86+ from Grub, it's a good starting point

Try to edit /etc/defaults/grub and set:
GRUB_CMDLINE_LINUX_DEFAULT="noplymouth"

then run update-grub!

Thank You for the answers.
After a complete pass of Memtest86 i get Errors: 0.
Moreover, i install from CD the Ubuntu Server 12.04 64bit and try to reboot the server more than 30 times, without any error.
During the boot now the log messages before the "Adding swap ..." are:

 [ 4.657586] init: ureadahead main process (299) terminated with status 5
 [ 4.936844] Adding 15625212k swap on /dev/sda3. Priority:-1 extents:1 across:15625212k FS

without any log related to "plymouth-upstart-bridge".
Before apply the suggestion of Thomas i need to reinstall the 14.04.
Can i provide you some more information before reinstall the 14.04 ?

Try:

echo "megaraid_sas" | sudo tee -a /etc/modules > /dev/null

Reboot to test. Possibly related to:

I try the following:
echo "megaraid_sas" | sudo tee -a /etc/modules > /dev/null
without success, then restored the origina /etc/modules file.

edit /etc/defaults/grub and set:
GRUB_CMDLINE_LINUX_DEFAULT="noplymouth"
with update-grub!
without success: the only difference is tha lack of the log messages:

init: plymouth-upstart-bridge main process (232) terminated with status 1
init: plymouth-upstart-bridge main process ended, respawning

The problem does not appera in various VM where i installed the same Ubuntu Server 14.04 64bit.

Is it ok with Precise (Ubuntu 12.04)?

Revision history for this message
luciano rinetti (l-rinetti) said : 		#7

Yes, no problem with the 12.04 (same HW, same system, same conditions).
With the 14.04 the problem appears:
- after a fresh install
- after a fresh install and after apt-get-update + apt-get dist-upgrade
Moreover, after the boot, the system show me the GRUB splah page and wait forever my choice (i choice Ubuntu) before complete the boot process.

I try to use two different HD (Seagate 2TB in RAID1) and repeat all the 14.04 Ubuntu Server 64bit install procedure, this time with automating partitioning (what the install procedure proposed). But nothing change, during reboot the system stop as described above.
