Another problem on this UML box is that if I do tail -f on some file, I ocassionally get an assertion: tail: xnanosleep.c:67: xnanosleep: Assertion `0 <= seconds' failed. This seems to happen more often (or at all) when I am doing something using the openssl - tail -f on an apache access log runs fine when I am doing http accesses and fails quite repeatedly when I am doing https or starting/terminating new SSL connection from/to the box. I also have a few strace-s from the failing sshd, where I can't really understand how the code got there. These two have one thing in common - a double variable that got initialized long ago and at the time of the problem it looks like it mysteriously changed value: "entropy" in the case of openssl and "sleep_interval" in tail. Am I seeing ghosts? Anyone got other mysterious problems with current UML kernel? Could it be that some state-saving method is corrupting fp registers or something like that? Was there some change in the UML / vanilla kernel recently? To the openssl-ers: I am starting to think that openssl is fine here and that the problem is indeed in the UML kernel.
