 |
|
With 0.96-r2 when I try to boot a kernel that worked fine with 2 GB installed I get an error stating that the kernel is to big to fit in memory. Is their a patch for this or is everyone with > 4GB of memory using lilo?

I found a bug report and patch for the problem here: http://savannah.gnu.org/bugs/?func=detailitem&item_id=9954
It is from 2004 though, and I would have thought GRUB would have been patched and fixed by now.
The version that bug report refers to is 0.95+cvs20040624 |

Thanks for the link. I will try this when I get a chance.
[EDIT]
I tried it and after a few setps I was able to get it working. The version grub that I use (0.96-r2) was newer than the patch so the patch failed but it was pretty easy to fix. I made a .patch and a new ebuild grub-0.96-r3.ebuild. I guess I could post them along with a bug report at bugs.gento.org.
[/EDIT]

To install. Make sure you have your PORTDIR_OVERLAY setup in /etc/make.conf
| Code: | cat /etc/make.conf | grep OVERLAY
PORTDIR_OVERLAY="/usr/local/portage"
|
Then enter the following commands:
| Code: | mkdir -p /usr/local/portage/sys-boot/grub
cp -r /usr/portage/sys-boot/grub/files /usr/local/portage/sys-boot/grub/
cd /usr/local/portage/sys-boot/grub/
|
Then copy and paste the two files above and then run the following command:
| Code: | | ebuild grub-0.96-r3.ebuild digest |
Then setup your keywords for the emerge so that in the future grub does not accidently be overwritten by a new version without the patch:
| Code: | mkdir -p /etc/portage
echo "=grub-0.96-r3 ~x86 ~amd64" >> /etc/portage/package.keywords
echo ">grub-0.96-r3" >> /etc/portage/package.mask
|
Then you can emerge grub:
| Code: | | emerge =grub-0.96-r3 |

| How that is not in grub-0.97 is beyond me! Can we get a 0.97-r1 with that patch in it. I realize there are not a ton of users with over 2gb of ram, but there has to be enough out there to have people running into this? If you don't have time, I can submit the ebuild and patch to get a 0.97-r1 release. |

Please patch and file bug report for 0.97-r1 if you can. I am a little busy now and since both machines that have 4GB are in use 24/7 I really should not be doing any testing that could result in any downtime...

Thanks, guys, I was having the same problem, and this fixes it. I've created a patch and ebuild which I've posted to bugzilla:
http://bugs.gentoo.org/show_bug.cgi?id=111634
For the record, the grub error this fixes is
Error 28: "selected item cannot fit into memory".

I am glad to see there is now an ebuild with the patch for this in portage (0.97-r1), although I have not tested it.

I am attempting to install version .97-r1. After I run the emerge =grub-0.97-r1, I get the following.
--- Invalid atom in /etc/portage/package.keywords: =grub-0.97-r1
Calculating dependicies
!!! All ebuilds that could satisfy "=grub-0.97-r1" have been masked.
!!! One of the following masked packages is required to complete your request:
- sys-boot/grub-0.97-r1 (masked by: ~amd64 keyword)
Any ideas?
Contents of /ets/portage/package.keywords:
=grub-0.97-r1 ~amd64
Thanks. |

The "invalid atom" line says it all - it should be =sys-boot/grub-0.97-r1 ~amd64 in /etc/portage/package.keywords:

| I'm glad to see this getting resolved, it is quite annoying as I have 5 boxes with 4+ GB of ram. I ended up emerging grub-static instead of grub as a work around. |

So with grub-static does it works?
Or have I to add | Code: | | =sys-boot/grub-0.97-r2 ~amd64 |
to /etc/portage/package.keywords ?

| I'd try 0.97-r2 and see if it works. If you load grub-static you then have to use grub-install which can be a pain if you don't put the gentoo grub into the mbr. |

I ran into this today. It is a two years old Grub problem and it is not fixed in the source of Grub, yet!
Imre
Added new Info:
OK. So you do not need the patching magic mentioned above. We should close this thread. The solution is in portage tree grub-0.97-r2. You need to unmask and do a couple things. See this thread:
http://forums.gentoo.org/viewtopic-t-421919-highlight-selected+item.html
This is from that thread and solves the problem:
(1)
ACCEPT_KEYWORDS="~x86 ~amd64" emerge -f =grub-0.97-r2
(2)
cd /usr/portage/sys-boot/grub
ebuild grub-0.97-r2.ebuild digest
(3)
echo "=sys-boot/grub-0.97-r2 ~x86 ~amd64" >> /etc/portage/package.keywords
(4)
emerge grub |

| I just tried to install Gentoo onto my new Dell PowerEdge 2950 with 16GB of RAM and I believe I have run into this problem. Seeing as I am having network connectivity issues from the new machine as well, does anyone have any suggesstions as to how to load GRUB onto the machine so I can boot it? Thanks. |

Just letting you guys know this isn't an issue with Grub version 0.97-r3. I ran into this error installing off the 2006.1 cd which installed grub 0.96, after upgrading everything is fine. This was on a Dell PowerEdge 2950 with 4GB RAM. |
