Hi Scott et al -
I have an older Supermicro 370DL3 SMP motherboard with an Adaptec 2810sa
controller with 8 300GB SATA Maxtor drives attached in Raid5. Under
heavy load I get errors of the form:
aac0: COMMAND 0xXXXXXXXX TIMEOUT AFTER XXX SECONDS
When this occurs, the system is alive but the filesystem is hung. A cold boot
clears the condition. Under lighter loads it appears to be fine. The OS is
FreeBSD 5.3-RELEASE upgraded from source to 5.4-RELEASE with acpi disabled.
The problem is reproducible by extracting a large tarball which is present
on the filesystem to the same filesystem. What information do you need to
debug the problem?
