Hi all, wise gentoo users!
I've recently bought an extra GB of RAM for my laptop. After inserting it, kernel refuses to boot, it hangs at "Booting the kernel"
I'm sure there's nothing wrong with the RAM, so it must be some other issue, perhaps related with my boot options?

Well, if you haven't changed anything else other than the RAM module since the
last time you booted the machine, then the problem would not be with your
Grub configuration . . . If you have, then revert the change.

Boot a LiveCD and run memtest86. Sometimes even new memory modules are duff.

The first thing is to re-insert the RAM very carefully,
then to check that no other connections got dislodged accidentally.
Just my bit of Gentoo wisdom (smile).

Just a thought... Did you enable High Memory support in your kernel?
Processor type and features --->
High Memory Support --->

Nothing to do about it...
If he's using amd64 that option doesn't even exist.
And even if he's on x86, if that option is not enabled, it will boot, but will just not use all the memory phisically available.

I don't know if you've tried this one already but another idea would be
to enter the system setup (BIOS) and just save the changes, then reboot.
You used to have to do this after any physical changes with RAM, though
I haven't seen it in years.
Just something else to try.

How? Have you run memtest?

No kernel boot after inserting more ram
An alternative to running memtest (which is quite easy to do, I might
add) would be to remove the original RAM and see if the computer boots
with the new RAM only.
Alternatively, you could just run memtest, as it is included with many
BIOSs now. It doesn't take long to identify problems, if there are any.
I find that test #5 is the best test for finding problems, however it
tends to keep you in the dark until it's finished the test.

No kernel boot after inserting more ram
Following your replies I've done the following, in an attempt to isolate the problem:
(memory #1 - "old" memory, memory #2 - new memory)
- Runned memtest on both memories with 0 errors
- Booted with both memories... kernel hang
- Booted with memory #1 on slot #1 successfully
- Booted with memory #1 on slot #2 successfully
- Booted with memory #2 on slot #1 successfully
- Booted with memory #2 on slot #2 successfully
- Booted with both memories on windows successfully
For some reason, my kernel hangs if I have 2 GB of RAM installed.
And I do have High memory support (4GB), although that doesn't seem relevant.
Ideas? :X
Thank you all for the quick replies.
Cheers

No kernel boot after inserting more ram
Well, after all kinds of tests and trying different types of memory configurations, I can only conclude that my kernel boots normally with 1 GB of RAM installed but hangs when I have 2 GB of RAM installed. I can't find a logical reason for this to happen.
Any pointers or suggestions are welcome,
Regards
