[Kernel-packages] [Bug 1386973] Re: Ubuntu 14.10 soft lockup with ATI Radeon R7 250 X
@federicotg You should submit this patch to upstream [1] and get some comments/review for this patch first. Looking upstream I don't see any obvious fixes for this. Thanks for debugging!

[AMD/ATI] Cape Verde XT [Radeon HD 7770/8760 / R7 250X]. When I boot from the Utopic DVD I get to the language menu and I can select try ubuntu without installing, but after a few sencods I get BUG: soft lockup - CPU#0 stuck for 22s!' and the message just repeats every 22 secods forever. I tried setting nomodeset using the F6 menu, but I got exactly the same result. This is Ubuntu 14.10 64 bits which basically seems unable to boot with that hardware. The experience was the same with 14.04, but I thought 14.10 would be better. In 14.04 disabling the video card and booting off the integrated graphics let me set nomodeset in /etc/default/grub and I was able boot with the R7 250X with the VESA driver.
