Hi Hans,
sorry to bother you again - but maybe you can help me:
I recently installed the new Ubuntu 9.04 release containing kernel 2.6.28-11.
The ChangeLog contains the info, that upstream kernel changes from 2.6.28.8
were incorporated, amongst others the line:
V4L: ivtv: fix decoder crash regression
I thought this was the patch for the problem you solved in February.
But after installing the new release, I had once a crash with the same message
as previously ('unable to handle kernel paging request'). It is not as
reproducible
as before, but it seems to be the same error.
I had a look at 'ivtv-ioctl.c' and recognized that the code sequence
'case IVTV_IOC_DMA_FRAME: ... return ivtv_decoder_ioctls(...' is still in
function
'ivtv_default()' and not in 'ivtv_serialized_ioctl()'.
Am I right in assuming that the Ubuntu guys have failed to incorporate the
patch or may I have missed something?
Best Regards,
Johannes
