["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

elhoir, the next step is to fully reverse commit bisect from kernel 4.4
to 4.5-rc4 in order to identify the last bad commit, followed
immediately by the first good one. Once this good commit has been
identified, it may be reviewed for backporting. Could you please do this
following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.

Thank you for your understanding.

  EIP:asus_sysfs_is_visible

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  hello,
  i have been hitting this since 4.4.0 linux kernel.
  It boots fine so it doesnt make system unbootable.

  I think this has something to do with the asus_laptop module (my
  laptop is ASUS), but im not sure.

  I attach the complete dmesg output. BUG is at line 830.
