And it is a BUG, because the kernel log says it is a bug:
[18892.976044] BUG: unable to handle kernel paging request at ffffc90012825250
There is no more confirmation needed. It IS a BUG.
Yes. But it's apparently a bad pointer dereference in the timer code => most likely a nasty race condition. That is usually not easily solved by "just looking at logs and code". Sorry.
No, what I mean is that it is easy to identify that there is a bug without me having to find other people with the same problem - not that it is easy to solve. In this case, I was for weeks able to reproduce the failure at will and obtain more data, if they asked. They did not. They ignored me.
Now I know that reporting bugs against distro kernels is sometimes hard, simply because it is often the case that the distro's kernel maintainers are also busy with developing the mainline kernel. So the first thing I do is: I try if the bug is still present in the latest Kernel:Stable kernel, and if so, if it's still present in the latest Kernel:HEAD kernel.
For that, they could ASK. As I said in the report, I had a test setup rigged up, found the problem, investigated, for several days, maybe weeks, and reported. In deference to bugzilla people, I kept that setup untouched for some weeks, then I had to move on and use the hard disk. Nobody was interested. It affects reiserfs, and that is doomed.
For this particular bug, it might just be bad luck that reiserfs is no longer really actively maintained by anoyone? I don't know.
Possibly. But you see, I spent a long time investigating an issue and obtaining data, having to rig a second computer to record the logs during the crash, and first having to find how to do that, and all for nothing. Happened a few times to me. Which is the main point: it is discouraging to report in Bugzilla if nobody listens. Not even a thankyou, we read you, but we are understaffed. - -- Cheers / Saludos, Carlos E. R.
