The issues are listed in this link, but I'll relist/summarize here:
Ubuntu 15.04 is locking up on me, primarily when watching internet videos or listening to Slacker Radio. I have Ubuntu installed on a Gigabyte F2A88XM-D3H with an AMD A10-7870k, 8 GB ram (2x 4GB) and an Antec Green 380 PSU. Memtest reports no errors on 5 passes over 14 hours, but displays RAM as 7111 MB DDR2 (not DDR3, it's not a typo) when UEFI BIOS reports correctly 8192 MB DDR3, and Ubuntu displays 7020436K in "free" so I'm not sure that the RAM isn't the culprit. "sensors" reports 0°c or below freezing temps, but BIOS shows 57°c max for CPU when it is left for several minutes to find equilibrium so I don't think heat is a problem.
I've seen recommendations saying everything from flash being unstable to any one of my core components being faulty, and I'm really not sure where to go from here. Please assist.
Additionally as requested, output of
lspci -k | egrep 'VGA|Display' -A2
andrew@mediacenter:~$ lspci -k | egrep 'VGA|Display' -A2 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri [Radeon R7 Graphics] (rev d4) Subsystem: Gigabyte Technology Co., Ltd Device d000 Kernel driver in use: radeon
I installed the
fglrx proprietary driver and have rebooted. I have tested with Firefox, Chromium, and Google Chrome and they all still freeze up the computer. Using
[alt]+[SysRq]+[R][E][I][S][U][B] works if I do it shortly after the freeze, but if I wait just a few seconds it does nothing.
lspci -k | egrep 'VGA|Display' -A2 now reports
Kernel driver in use: fglrx_pci
Additionally, I have been running Ubuntu from the installation media (a 8 or 16 GB flash drive) for over 5 hours now with Google Chrome installed playing YouTube videos with no problem.
Sometime between the 5 hour mark and now (13 hours later) the LiveCD locked the screen and xorg crashed. However, the computer never locked up/hard froze.
Is it possible that some of the files are corrupted for the installation portion of the drive? I'm going to redownload 15.04, recreate the bootable flashdrive, and reinstall Ubuntu to see if that was the problem this whole time.
As it turns out, flash is likely not related. I was booted into the system running disk diagnostics (
badblocks and disk utilities) having not started a web browser at all since boot, and I still got a freeze. I'm now believing that an update or hardware are causing the system failures and the web browser/flash is fine. I'm currently booted off the live "CD" (USB flash drive) and running
badblocks on the hard drive.
Is there possibly a log of sorts that I can inspect that might help diagnose the crash?
