Bug: Soft Lockup during 10.04 install

Asked by David Bell

I am trying to install 10.04 on my old Toshiba Satellite A105 laptop. When booting the CD i get the following messages:

init: ureadahead-other main process (1091) terminated with status 4
init: ureadahead-other main process (1092) terminated with status 4
[125.628008] BUG: soft lockup - CPU#0 stuck for 61s! [modprobe:1315]

Then it continues giving me that same error with the [###.#####] changing each time. I found some suggestions for a workaround using nomodset as a kernel parameter, but i don't want to have to do that every time i boot up. Any suggestions?

Well you can add the nomodset option permanently to the boot parameter by setting GRUB_CMDLINE_LINUX_DEFAULT=" quiet nomodset splash" in /etc/default/grub and then doing : sudo apt-get update.
This way you wont have to put it everytime you reboot

I'm a newbie at this and I'm trying to install ubuntu 10.04 onto a Sony PCG-FAX53 laptop. I've replaced the HDD recently with a newer drive as the original was possibly bad and small(30GB).

I can get Ubuntu to run off a CD in the tray, but when I go to install it hangs. It hung up at 60% completion this last time.

Anyone else have this issue that can give me some pointers how to get this thing to finish?

I have 512mb of RAM installed so that shouldn't be an issue.

Should I consider Xubuntu instead?
