You can download this test kernel (or newer) from http://people.redhat.com/jwilson/el5

Detailed testing feedback is always welcomed.
Comment 7 Gris Ge 2011-06-02 06:01:04 UTC 
Reproduced this problem on -194 kernel by using the reproducer c code.

The I/O error not gone after disk online.

Using this command for bring disk offline:

echo offline > /sys/block/sdb/device/state && sleep 1 && echo running > /sys/block/sdb/device/state


On -264 kernel, problem fixed.
