Christopher, I am not sure regarding your proposed strategy...
Let me explained :
- when I first discovered & reported this issue, I was using Ubuntu 15.04 / kernel 3.19.0-28-generic #30-Ubuntu on x86_64
- then I thought it was resolved when upgrading to kernel 3.19.0-39-generic (now I more think that I had some luck it did not appear as I am actually not able to reproduce it easily)
- I upgraded to Ubuntu 15.10 / kernel 4.2.0-22-generic and the issue is still there
- I tested latest mainline kernel 4.4-rc7, issue is present

To me, applying bisect on the 3.19-4.2 range will probably not lead to
any good result as I expect all kernels to show up the issue.

I would rather look for issues on the 3.16-3.19 range...

Let me know if I missed something.

Title:
  r852 & r592 IRQ: DMA errors cause log files to grow *HUGE*

Status in linux package in Ubuntu:
  Incomplete
Status in linux package in openSUSE:
  Fix Released

Bug description:
  Hi,
  I have many crash messages related to r852 & r592 modules in my syslog files.
  I had already submitted a bug report for that ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1500156 ) but since that time, I upgraded to 15.10. The issue is still there, but displayed a bit differently (stack trace now).
  This issue slows down the machine and can also lead to a disk full in /var/log I guess. My current syslog is about 4GB large and is 1 day old.

  Typical messages I get :
  [104370.032867] r592: IRQ: card added
  [104370.032873] r592: IRQ: DMA error

  I've read some posts/other bug reports related to the same issue :

  I would be glad if some solution is proposed to stop filling these
  logs !

  Cheers,

  Laurent
