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... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/883646 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.
