[openib-general] [PATCH][SDP] AIO buffer corruption

[Steven Wooding]

Libor,

Here are the details of my setup:

HCA: PCI-Express MT25208 (MT23108 compat mode) with 256MB memory
HCA Fireware: 4.6.2
Command: ttcp.aio.c.x -r -fM -a 8 -l 2048
                   ttcp.aio.c.x -t -fM -a 8 -n 10000 -l 2048 {ip of 
receiver}

Syslog: Get the following message with sucessful transfer, but not with 
-32/-104 error
             Kernel: ERR: IOCB <0> cancel <0> flag <00e4> size <{-l}:0:{-l}>

SDP Debug: Get the following message with all ttcp.aio.c.x runs
             Kernel: WARN: <9> <0101:3b01> CM state <0> event <9> error <-2>

I'm away for two weeks, so I'll get back to you with any further info 
you require when I get back.

Cheers,

Steve Wooding.
