I learned to not to trust Linode after incident around 2012-01-23: I emailed them asking if they would compile a new kernel without the /proc/pid/mem local root exploit; they manually patched and compiled a new 3.2.1-linode40 kernel. I booted into it, but it repeatedly locked up my VPS after ~10-12 hours of runtime. No monitoring or automatic reboot on their side, and both lockups happened right before I went to sleep. Did they bother notifying anybody about their buggy kernel, which many people probably booted into? Nope. Nothing.
