Hi:
Sometimes I get a very weird issue with current kernels and my Intel SSD 80GB (second gen) SSD drive.
Hardware Class: disk Model: "INTEL SSDSA2M080" Vendor: "INTEL" Device: "SSDSA2M080" Revision: "2CV1"
Under somewhat heavy I/O the kernel "thinks" the drive is broken.

and disconnects it for no more than 2 seconds, system microfreezes and then resumes working perfectly.
The problem is that it happends barely once a week if any, so it is very hard to track down,
The drive is less than 4 months old and works flawlessly otherwise.
Is this a SSD firmware, BIOS, SATA controller or kernel bug ?
Just in case someone else hits this problem, intel apparently has fixed this issue 18 January 2011 Firmware version : 2CV102M3 This firmware revision fixes enumeration and slow-boot issues on SATA 6Gb/s controllers, adds improvements to S.M.A.R.T. attributes for more accurate reporting of drive health, improves NCQ capability, and fixes possible drive hangs when reading S.M.A.R.T. self-test log. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
