Public bug reported: portion of bug report for bionic:
Newer 4.15 kernels contain the following fix for CVE-2018-1108: 43838a23a05fb ("random: fix crng_ready() test") This causes cloud-init to stall for a potentially long time during boot (waiting for entropy I presume). Google reported boot delays of 75 minutes. I've tracked this down to the following import in templater.py which causes the delay: from jinja2 import Template as JTemplate Which is called when cc_update_etc_hosts is imported. NOTE: I'm experiencing this with focal repeatedly - just hangs forever! ubunutu 20.04 server - live ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1880334 Title: Cloud-init causes potentially huge boot delays with 4.15 kernels Edit To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1880334/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
