Hi,
I'm wondering if this could possibly be related to a problem I was
having with my 4.9-RELEASE box. Twice in two days it hung on me
completely, and started spouting the following error messages:
ad0 WRITE command timeout tag=0 serv=0 -restting
ad0: trying fallback to PIO mode
ata0: resetting devices .. done
fxp1: device timeout
fxp0: device timeout
The ad0 WRITE message and the ata0 message repeated multiple times. So
did the fxp messages, but they varied.
The only thing I could do was reboot the machine. I cloned the drive, as
web research suggested a faulty harddrive might be at fault, but the
same hang-up occured.
I'm currently experimenting by reverting the box back to 4.8-RELEASE to
see if I can reproduce the hang there.
I've attached my 4.8-RELEASE dmesg for informational purposes.
Cheers,
DMK
