Hi. I've tried to install Steam using lemul branch. I've used c6 ports, installed x11/linux-c6-xorg-libs and x11/nvidia-driver (I have NVidia GPU). I've also loaded linux, linux64 and linprocfs modules and mounted linproc, proc and fdesc. When I try to install Steam, screen freezes (having run 'brandelf -t linux steam' before) and some artifacts appear. Mouse cursor disappears and I can't switch windows (using alt+tab) nor can I switch to tty. After a hard reboot, I can see following lines in /var/log/messages: Feb 1 20:57:07 lemul kernel: acquiring duplicate lock of same type: "os.lock_sx" Feb 1 20:57:07 lemul kernel: 1st os.lock_sx @ nvidia_os.c:609 Feb 1 20:57:07 lemul kernel: 2nd os.lock_sx @ nvidia_os.c:609 Feb 1 20:57:07 lemul kernel: KDB: stack backtrace: Feb 1 20:57:07 lemul kernel: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe023a361460 Feb 1 20:57:07 lemul kernel: witness_checkorder() at witness_checkorder+0xe54/frame 0xfffffe023a3614f0 Feb 1 20:57:07 lemul kernel: _sx_xlock() at _sx_xlock+0x75/frame 0xfffffe023a361530 Feb 1 20:57:07 lemul kernel: os_acquire_mutex() at os_acquire_mutex+0x32/frame 0xfffffe023a361550 Feb 1 20:57:07 lemul kernel: _nv013366rm() at _nv013366rm+0x18/frame 0xfffffe000249be90 Feb 1 20:57:07 lemul kernel: dmapbase() at 0xfffff8008b245b00 Feb 1 20:57:07 lemul kernel: acquiring duplicate lock of same type: "os.lock_mtx" Feb 1 20:57:07 lemul kernel: 1st os.lock_mtx @ nvidia_os.c:783 Feb 1 20:57:07 lemul kernel: 2nd os.lock_mtx @ nvidia_os.c:783 Feb 1 20:57:07 lemul kernel: KDB: stack backtrace: Feb 1 20:57:07 lemul kernel: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe023a361100 Feb 1 20:57:07 lemul kernel: witness_checkorder() at witness_checkorder+0xe54/frame 0xfffffe023a361190 Feb 1 20:57:07 lemul kernel: __mtx_lock_flags() at __mtx_lock_flags+0xa8/frame 0xfffffe023a3611e0 Feb 1 20:57:07 lemul kernel: os_acquire_spinlock() at os_acquire_spinlock+0x1b/frame 0xfffffe023a3611f0 Feb 1 20:57:07 lemul kernel: _nv015308rm() at _nv015308rm+0xce5/frame 0xfffffe000249ef10 If you have any further questions, I will try to help.
