R: [cpia] USB CAM crash

[Piero Campanelli]

Hi

The patch is present in the kernel pre6 (i have seen this code in soruce
kernel)...so I think the problem is more serious :-)

This is the report for today:

Started at 9.00 am
Crash at 9.43 (reboot)
Crash at 15.30 (reboot)

At the moment is live....

I do every 56 second a

vidcat -f jpeg -d /dev/video1 ...

Byeee

: Look at the file cpia.c. Starting from the line 1579
: you should see the code from the patch:
:         retval = cam->ops->transferCmd(cam->lowlevel_data, cmd, data);
: -       if (retval)
: +       if (retval) {
:                 DBG("%x - failed, retval=%d\n", command, retval);
: -       else {
: +               if (command == CPIA_COMMAND_GetColourParams ||
: +                   command == CPIA_COMMAND_GetColourBalance ||
: +                   command == CPIA_COMMAND_GetExposure)
: +                       up(&cam->param_lock);
: +       } else {
:                 switch(command) {
:                 case CPIA_COMMAND_GetCPIAVersion:
:                         cam->params.version.firmwareVersion = data[0];

: I did not recompiled my kernel yet to verify the fix.
