>Description:
When using a motherboard with SIS 962 IDE controller the system doesn't boot up it hangs with the follwing nessage:

ad0 : read command timeout tag=0 serv=0 resetting
ata0 : resetting devices..

Then the system is blocked even CTRl-ALT-DEL won't work.

The computer is a ASUS Barebone:

With FreeBSD 5.2.1 this issue seems to be solved. FreeSBee boots.

>How-To-Repeat:
Just reboot ;)
