Hi folks,
I'm seeing a problem on all the kernels that are 2.4.13pre1 and up. I've lost the ability to communicate to my storage through some qlogic 2200 fibre channel cards. All the disks are identified and given over to devices. The problem occurs when you attempt to write to the disks. The system prints out that the link is up, but will not move from there. The system becomes unresponsive to the keyboard. Up to 2.4.12 works ok (I'm putting together some comparative numbers), and the current ac tree is working correctly as well.
I saw this behavior with 2.4.10 and the bounce memory patch by Jens Axboe, but attributed it to operator error. I'm less sure now.
Any ideas about what is going on would be appreciated. I know this is a sketchy description, but I'm hoping someone else has seen it too and can help me get closer to a resolution.
