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.

What I did:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

It essentially upgraded the kernel without making my hands dirty with patching the kernel myself.

I am not sure if it will help with my boot fail issue - have to boot a few times to see but I will report back. As far as the question is concerned, it is resolved.

The bug was fixed by upgrading the kernel, but this doesn't answer the opening question and is unsatisfying for everyone arriving here hoping for an answer.

So, how does one, generally, patch a kernel bug when patch files are available?
