Bug#466598: grub-pc chokes on grub.cfg, hangs before menu
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I'm sorry, I gave you attitude when I was frustrated. You didn't deserve that. I didn't edit grub.cfg, and this is not the first time I installed grub-pc. I've been using grub-pc for a few months. The edits I did do consisted of commenting out lines. I don't know the syntax, but I understand enough to figure out what a conditional block looks like. When the new version came out, I took a snapshot of the virtual machine I was testing on and held my breath. The problem seems to be I can't hold my breath long enough. If I wait a bit longer I get a menu. The menu is slow to the point of unresponsive, but I get a working system if I wait for it to pick the default. At this point I assume all of grub2 executes at ring 0 and the slowdown is due to virtualbox moving all of it to ring 1. I'll reinstall grub-pc on my tower and see if it's fixed. If so, I hope I didn't waste too much of your time. Despite my complaints, I like grub2 a lot and I'm really impressed with the progress it's made.

Hi Barry, On Wed, Feb 20, 2008 at 09:30:36AM -0500, Barry Schatz wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I'm sorry, I gave you attitude when I was frustrated. You didn't deserve that. Apologise accepted. I didn't edit grub.cfg, and this is not the first time I installed grub-pc. I've been using grub-pc for a few months. The edits I did do consisted of commenting out lines. I don't know the syntax, but I understand enough to figure out what a conditional block looks like. It is easy to make assumptions but the syntax is actually fragile. While code generated by update-grub is well-tested and known to work, some minor details can break stuff unexpectedly. So please, generate grub.cfg with update-grub and try again. There _was_ a bug in the parser in an older release, but if you hit that all you have to do is grub-install the latest version; no need to hand-edit grub.cfg. If I wait a bit longer I get a menu. The menu is slow to the point of unresponsive, but I get a working system if I wait for it to pick the default. So it works then? At this point I assume all of grub2 executes at ring 0 and the slowdown is due to virtualbox moving all of it to ring 1. Could be. There's really not much GRUB can do to slow down your system. Either it's using the CPU (fast) or calls the BIOS (slow or fast, who knows?). -- Robert Millan GPLv2 I know my rights; I want my phone call! DRM What use is a phone call… if you are unable to speak?

Bug#466598: grub-pc chokes on grub.cfg, hangs before menu
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Package: grub-pc
Version: 1.96+20080216-1
Severity: critical
Justification: breaks the whole system
Using the newest grub-pc package, I ran update-grub and then
grub-install. Chainloading doesn't work by the way, because
it doesn't create the chainload option in legacy grub. Booting
straight to grub2 results in Welcome to Grub and an
unresponsive computer.
In a previous release the if statements created by 00_header
PROVIDED BY THE GRUB-PC PACKAGE were a problem, but removing
those if statements doesn't avoid the problem any more.
I have had this problem on two computers, one a desktop and
one a virtual machine.
