I am deploying 2.6.34.8-15 on many machines successfully.
With about 10 HP Workstations I regularily get the following message in the kernel log:

I also experience severe data loss whenever such an error occurs.
I can suggest two things to do: (1) Extract the SMART log from the drive just after the problem occurs to see what it thinks has happened. (2) Try a recent kernel on an affected machine (e.g. either install opensuse Kernel:STABLE or just run Knoppix) and see if it cures the problem. Then you would have both a workaround and a strategy to isolate the problem. Also, how does the hardware of the affected machines differ from similar machines where the problem does not occur? Disk type or number of disks? Motherboard? etc. Cheers, Dave -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
