This happens on a fully updated Slackware64-14.2 system with tor after an update to kernel 4.4.118 that fixes Spectre variant 1. Same version of tor worked fine with a few previous 4.4.x kernel versions (4.4.115, 4.4.111, 4.4.88). Tor process freezes in uninterruptible state as soon as a program anonymized using this guideline tries to get online. Symptoms are similar to the ones described in this ticket
