I have one system with a fanless radeon card :: |
| 26 |
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. |
| 27 |
[AMD/ATI] Cape Verde PRO [Radeon HD 7750/8740 / R7 250E] |
| 28 |

that goes blank, locks keyboard and requires a hard system reset, |
| 31 |
sporadically.Sometimes months, sometimes a few days. It always comes |
| 32 |
back fine after reboot. Numerous memory scans finds nothing wrong with |
| 33 |
ram. It locks up sporadically, unrelated to load/hardware usage, neither |
| 34 |
specific to an application. I suspect the video driver and associated |
| 35 |
codes, but have not found it. Then again, I have not looked in a robust |
| 36 |
manner. If you look at Phoronix, there is heavy work on most aspects of |
| 37 |
the greater AMD/radeon area of linux. |

I just hope some more modern fanless video cards (radeon) become |
| 41 |
available, as what I use is old. I was/am preparing to work on |
| 42 |
radeontop. Some folks boot windows and use vendor supplied diagnostic |
| 43 |
tools when a gremlin appears in the radeon hardware. My card(s) are so |
| 44 |
old, I'm waiting on newer fanless cards (have not looked lately to see |
| 45 |
what's is out there that is fanless, radeon and priced lower). All in |
| 46 |
all, I love radeon/AMD video cards; ymmv. |
| 47 |
|
| 48 |
|
| 49 |
radeontop needs tlc, so anyone could jump my efforts as that ebuild/code |
| 50 |
needs some updates. I'm not sure when I'll get to (proxy) fix it up; |
| 51 |
but it monitors the radeon cards by categories of GPU/resource |
| 52 |
utilization, if certain apps are killing your video/system. Not sure |
| 53 |
what new features are in the newer versions. I do have a plethora of |
| 54 |
older radeon cards to test, if somebody wanted to proxy maintain |
| 55 |
radeontop, as I'm not sure when I'll get to it. |
