Title:
Ubuntu 14.10 soft lockup with ATI Radeon R7 250 X
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have a VGA controller Advanced Micro Devices, Inc. [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. Installed
Catalyst afterwards.
