No objection.
I run for 12 hours some dd's (read and write in nullio) between initiator and target without any disconnection. Thus iSCSI code seems to be robust. Both initiator and target are alone on a single gigabit ethernet link (without any switch). I'm investigating...Can you reproduce on 2.6.22?
I cannot downgrade these servers on 2.6.22 due to a bug in FUTEX code.
Also, I do not think this is the cause of your failure, but you have CONFIG_DMA_ENGINE=y in your config. Setting this to 'n' will compile out the unneeded checks for offload engines in async_memcpy and async_xor.
