Hi Dan,

Please find attached the log that you asked me, with WARN_ON instead of
BUG_ON, and with the 2 #define DEBUG in dma.c and dma_v2.c.

Let me know if you want me to do more, or if you want to have access to
my server (in which case, provide me a public ssh key and sign your
email with PGP).

Thomas

P.S: I compressed the dmesg.txt because on debian lists if a message is
>= 40K, it requires administrator moderation, which I want to avoid.
