After installation of Slackware 9.0 with hotplug enabled
system reboots in couple of seconds after booting %)

Intel 845G chipset(82801DB/DBM USB, Ultra ATA, etc.)
with Celeron 2GHz CPU

Disabling hotplug enbales systrem to boot and work

Is there any fixes or something to do with?

It's a cruel BUG - many newbies are giving up seeing
system to reboot after just booting without a word
saying "See, this buggy Linux is NOT working!!!"

In better case they are moving to RedHat
