Public bug reported:
After upgrading from 10.04 I noticed a flood of message in dmesg like :
streamzap 3-1:1.0: streamzap_callback: received urb, len 2
streamzap 3-1:1.0: sz idx 0: f
streamzap 3-1:1.0: sz idx 1: ff
Has been for a while, but it finally got in my way enough to force me to
find out what was going on.
To reproduce it, looks like you just need a streamzap and to press some
buttons on it.
I think the problem is in the driver:
/drivers/media/IR/streamzap.c
in the function streamzap_callback
The lines:
dev_info(sz->dev, "%s: received urb, len %d\n", __func__, len);
and
dev_info(sz->dev, "sz idx %d: %x\n",
i, (unsigned char)sz->buf_in[i]);
which are the messages swamping dmesg.
I think what is meant to happen is that these lines are only done if
"debug" is true. Then you can control this logging with the
"/sys/module/streamzap/parameters/debug" file. But the debug variable
isn't acturally used and these lines are always executed if there is
data.
I emailed the maintainer and he said it was fixed four or five months
ago. So can we have this fixed back ported? Or at very least some
temporary fix. Compiling my own streamzap module every kernel release
would soon get as annoying as the dmesg flood. Especially for something
so simple to fix in the right place.
