patch

Sometimes I can't boot my laptop - it gets stuck here:

enter image description here

Then I have to do a hard-reset and it's fine. I checked the boot logs and this is what I think it's causing it (nevermind the timestamp inconsistencies):

[38.377595] BUG: unable to handle kernel NULL pointer dereference at           (null)
[38.377821] IP: [<ffffffffa01f6d7b>] r600_pcie_gart_tlb_flush+0xeb/0x110 [radeon]

[38.378214] Oops: 0000 [#1] SMP

Here is the full log.

I found the patches but I have no idea about which to use and how.

12.04 upgrade broke grub? (not wubi related)

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More
