Title:
System Hangs and General Protection Fault Occurs following NFS Access

Bug description:
Last night, in an attempt to secure my system against
Meltdown/Spectre, I upgraded from Zesty to Artful. Upon booting into
the latest kernel, my system would immediately hang and fail to
respond (including to SysRq commands).
Both this (my primary) system and an Intel NUC (which were both
upgraded from Zesty to Artful at the same time) export NFS shares to
one other. The NUC appears to be error-free, but my primary system
seems to crash whenever I attempt to access the NFS share of NUC.
As I have not tried any other kernel releases in either system other
than 4.13.0-25.29, it's impossible for me to say if this is an issue
regarding the recent security patch, or if it is some other issue.
Attached is the console log (obtained via netconsole) which includes
the kernel trace of the error.
Please let me know if further information is required or if I can help
further in troubleshooting.
