My notebook Samsung NP700G7A-S01PL was working stable for more than 2 years. I was using 3.11, 3.17, 3.18, 3.19 (since rc1) and many more successfully. First hang has happened on 2015-02-08 (23:30) with 3.19-rc5 I was using for 3 weeks.
So what I'm seeing are two possibly related problems: 1) Random hangs I don't have to be doing anything unusual. A single display, no UVD, just writing some code in kate. And then it randomly happens. My screen goes all white or green vertical lines or blue vertical lines. I can't use/access my machine, sound goes into a loop (last second). Sometimes it happens after hours, sometimes 30 minutes, sometimes few minutes. So far I got 5-7 hangs like this. 2) Init problems Unfortunately rebooting does not always help. Even cold boot (removing power & battery, keeping power button pressed for few seconds) isn't helpful. a) First I get UVD init errors: *ERROR* UVD not responding, trying to reset the VCPU!!! b) Then machine hangs after displaying "pitch is 7680" I've tracked it to be somewhere near register_framebuffer (see attached bad.txt) As long as I don't use radeon (booting with "nomodeset") it works stable. I tested my RAM with MemTest86 (one pass, took 1 hour), no errors, CPU temperature didn't exceed 70 degrees. This evening as the last hope I installed fglrx. It hangs my machine as well with following messages: [ 36.472526] console [netcon0] enabled [ 36.473106] netconsole: network logging started [ 48.192215] fglrx_pci 0000:01:00.0: irq 56 for MSI/MSI-X [ 48.192726] <6>[fglrx] Firegl kernel thread PID: 1481 [ 48.192833] <6>[fglrx] Firegl kernel thread PID: 1482 [ 48.192954] <6>[fglrx] Firegl kernel thread PID: 1483 [ 48.193077] <6>[fglrx] IRQ 56 Enabled [ 48.240118] <6>[fglrx] Reserved FB block: Shared offset:0, size:1000000 [ 48.240122] <6>[fglrx] Reserved FB block: Unshared offset:3fab4000, size:4000 [ 48.240124] <6>[fglrx] Reserved FB block: Unshared offset:3fab8000, size:548000 [ 48.240126] <6>[fglrx] Reserved FB block: Unshared offset:7fff3000, size:d000 However if I drop fglrx.ko and just use Xorg driver fglrx_drv.so it works stable. Any ideas? Is GPU on my motherboard just dying? :| -- RafaÅ -------------- next part -------------- [ 35.114273] [drm] radeon kernel modesetting enabled.
