hw_random: RNG not detected
Author
Geeze, this thing is giving me a headache...
I finally installed ubuntu on my laptop. Boy was that a mistake. When i try and start it up i get the message "hw_random: RNG not detected" somewhere in the boot proccess (either late in LILO's lifetime or early in ubuntu's) and i haven't the slightest clue how to fix this. I've been told to simply remove the module, but I don't know for sure how to do that, and i sure as heck don't know how to do that lacking even a bash console.
So what do I do?
thanks a ton

Which version of Ubuntu are you using? I don't recall hw_random being loaded in the versions I've used and I don't quite see why it wouldn't boot because of the failure to load it.
Anyway. There should be some other boot option (e.g., "recovery mode" or single user mode) at the LILO menu. Try to boot to that. Or, if you're comfortable enough to know how to do it, use a Live-CD and the mount the root or "/etc" partition (whichever has "/etc" in it) read-write. Open "/etc/modules" in a text editor and see if there's a line with "hw_random" on it. If so, remove it. If not, I'll try again :).

Thanks a lot for that. I really appreciate it. Now you said to change things at LILO's boot menu... may I ask how i get to LILO's menu? I don't know jack about LILO (and i'm a linux n00b to boot). But I understand the LiveCD approach, and I may very well do that, but for future reference could you explain the LILO technique to me? I'm not in a position to try either till later today. But thanks a ton for it all!

Hrm, when I tried the LiveCD which definitely worked on my other computer (desktop) and i THOUGHT had worked on my laptop as well, it failed at "starting hotplug subsystem". I'm going to see if the liveCD works on this computer (desktop) but I would appreciate alternative method's in the meantime
thanks

I haven't used LILO in a bit, so I'm a little rusty. If you want to skip the menu thing or it's not being shown: try typing "linux single" and hitting enter ("linux 1" might work also, but try single first).

When/where do i type "linux single" ? I don't have control over input at any point before the problems (in both cases) other than f2 to enter bios setup

Oops, sorry. Hold shift or alt after your BIOS is done but before LILO prints "LILO" to the screen and it should offer some interactivity.
i thought ubuntu only uses grub, not lilo. i think the grub menu also had a "recovery mode" boot option that boots the system into single user mode (init 1) to let you fix any problems.
Author
Thanks both of you. And for the record, ubuntu wanted to install lilo by default... it reccomended grub though... but i chose not to since i wanted my main partition to be xfs and apparently grub doesnt like xfs
thanks
