Under heavy disk read on my maxtor 40GB ata66 HD, freebsd locks up and
the following messages show up on the console.
ad4: READ command timeout tag=0 serv=0 - resetting
ata2: resetting devices...
At this point, the HD light is on, and the whole system locked up. I
have to do a hardware reset to reboot the system. This problem happen
several times and my system uptime is around 3 - 10 days because of
this.
1. Does anyone know what is wrong?
2. How to figure out where is the problem?
Harddisk (Maxtor), motherboard (Abit BP6), freebsd or whatever.
