HI I complained that to the linux-kernel but now aftter the testing I think dvb caused this hard crash. It starts by corrupted page table and machine is useless because although it didn't stop completely, almost every new process segfaults. memtest passes. I tested the machine on linux without dvb. Constant compilation of the kernel, and extra stressing of the gpu with nvidia binary module (kernel tainted), constantly running glxgears and opencl matrix computation on GPU. no sign of crash after hours of running, cpu at 59 deg C, cores at 79 deg C, GPU at 82 deg C. Then I removed binary nvidia module and used opensource nv (that doesn't taint the kernel). Crash happens when vdr-1.7.13 (debian e-tobi repository) is running and saa7134 dvb-t (compro videomate t750f) and saa7146 dvb-s (budget satelco pci) are loaded. VDR is tuned to a satellite program (DMAX Astra 19.2). I watch TV over dvb-s with vdr-sxfe as user. Watching is not necessary to cause the crash, vdr itself is enough. Best regards, Emard EXT4-fs (dm-16): re-mounted.
