On a Thinkpad T41p running Fedora Core 3 kept up-to-date since November. Recently, in the past two or three weeks, the clock has been incorrect every time I resume from ACPI suspend. Before that it was always correct when it woke up. Now the clock is always fast when it wakes up. It appears to be proportional to how long it has been sleeping, as if the clock were running consistently extremely fast while asleep, but I haven't run any tests to see if it is reproducible. I've been fixing it by restarting ntpd. I'm currently running kernel 2.6.10-1.741, but I've had all of the kernel updates since FC3 came out. I can't say for sure that the problem started with a kernel update, but it may have coincided with the first 2.6.10 kernel. Is this a known problem? Is there a fix?
