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.
