Subject: KMOD HASH kzalloc() error
Just tried 0.5 on Ubuntu 18.10:
Linux pax 4.18.0-11-generic #12-Ubuntu SMP Tue Oct 23 19:22:37 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux
gcc version 8.2.0 (Ubuntu 8.2.0-7ubuntu1)
Got the following (this was with 0.5 from tar.gz, then tried from
BitBucket and insmod just hanged, unable to kill):
