Comment 6 for bug 258357

I also did an "strace -r" on X, and determined that it does indeed hang for 30 seconds in a system call, and dies of a SIGKILL immediately afterwards. The relevant part of the log (the end) is this:

--------------------- from strace ------------------
     0.000047 stat("/dev/nvidia0", {st_mode=S_IFCHR|0660, st_rdev=makedev(195, 0), ...}) = 0
     0.000066 open("/dev/nvidia0", O_RDWR <unfinished ...>
    30.774676 +++ killed by SIGKILL +++
Process 10565 detached
-------------------- end strace ----------------------

So, this hang is in the kernel module, I presume. I'm not sure how to determine where in the kernel modules its hanging, though.

I have attached the entire strace below.
