[Berend Dekens <883646@xxxxxxxxxxxxxxxxxx>]

In general y I think that is true.

In this specific case however, the defect was part of an incomplete
driver which was part of the standard Ubuntu kernel. As upstream patches
for bugs are usually backported to the standard kernel of a specific
release and a 10 line patch was even supplied, this issue could have
been resolved in a matter of minutes.

Instead, the bug is rejected because the kernel issue became visible by
using a 3rd party user space program.

While I do not see the logic behind it, one might put that one on
policy. Next, the issue is reported by users with USB storage devices.
Now this *is* vanilla behaviour and indicates a kernel defect (once
again, with a solution provided - no upstream help is required as they
already fixed the issue in newer kernels).

As myself and collegues are using Ubuntu on (at that time) new hardware,
it was an active issue as the kernel log will fill up the root drive and
effectively break the system.

I agree that resources are scarce but when a problem and it solution are
handed over in a wrapped gift basket it is beyond me why it is ignored;
which brings me to my observation in #64...

Title:
  "ERROR no room on ep ring" fills up syslog and hard disk in minutes

Status in The Linux Kernel:
  Invalid
Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  I am running a fresh install of Ubuntu Oneiric 11.10 64-bit. After
  installing Gnome15 to use the extra features of my Logitech G15
  keyboard via the USB 3.0 connector on my system. The G15 is a low
  speed USB 2.0 device.

  Post from dmesg:

  WORKAROUND: Plug into native USB 2.0 port (from the Intel controller).

  I am now using 3.4.0-030400-generic from the Ubuntu Kernel Team and
  the error message no longer shows up!
