Description of problem: udev eats 100% of cpu for 5+ minutes when adding 32+ ttys using tty_register_device(). Version-Release number of selected component (if applicable): Latest "up2date" for everything on ES 4. How reproducible: Every time. Steps to Reproduce: 1. Add a driver to system that registers 32 ttys using the tty_register_device () call in kernel. 2. With or without a "rule" for those devices in /etc/udev/rules.d, it doesn't matter. Actual results: System will literally be bogged down for 5-10 minutes, system hasn't panic'ed, but is horribly unresponsive for those 5-10 minutes. An "uptime" will report load averages past 100!!! A "ps -ef" (when it eventually responses) shows 100's and 100's of: /bin/sh /sbin/hotplug tty /etc/hotplug.d/default/20-hal.hotplug tty Expected results: Very minimal cpu usage. The most important thing here is that under Fedora Core 4, 5 and 6, this isn't a problem at all! It works absolutely perfect uder FC 4, 5 and 6! Additional info: The udev version that appears to be in use on RH Enterprise 4 is "039". This is *very* *very* old compared to FC 4, 5 or 6. udev is currently up to "100" or so now! I am guessing that something in "udev" has changed in newer versionf of udev that makes things work a lot crisper. Why is udev not being kept up on RH 4?
