--- Comment #5 from JATothrim <jarmo.tiitto at gmail.com> --- I did more research and I was able to capture full kernel crash dump. Debugging the crashdump I found that The kernel dies at kernel version v3.18.19 in src lines: drivers/gpu/drm/radeon/radeon_mn.c:75 or drivers/gpu/drm/radeon/radeon_mn.c:76 on to NULL ptr dereference. At both code lines the kernel tries to lock a mutex apparently. I don't know exactly which one fails as I'm no expert debugging x86-64 assembly. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
