https://bugzilla.kernel.org/show_bug.cgi?id=14994 --- Comment #10 from Marc H. Thoben <kernelbug@xxxxxxxxxx> 2010-04-11 17:45:32 --- Hi Borislav, when I got the new hardware I bought it with an ATI card. For 2 weeks it kept crashing - no matter if ran the closed-source driver or without. Blaming the ATI driver I bought an Nvidia card and had the same problem. I ran Xorg with the nvidia driver, with nv and with vesa. It happened for all of them (yes, I made sure the kernel wasn't tainted by nvidia's driver). I found out about the netconsole module later, so I can't guarantee the problem now is the same problem as with the ATI card previously - but it for sure does seem so to me. I still have the ATI card here and could give it a try again if we need to know for sure. In the meantime I have compiled the ide-cd_mod module with the changes you suggested and got two nice & big dmesg to report. This time I loaded netconsole before syslog is started, so you can see all kernel messages. I hope that's what you meant with "whole dmesg" - otherwise I'm sorry for the spam in those logs. While doing tests I got one step further and I believe this is important: The kernel panic only shows up if there is no CD in the cdrom! For the first test I booted the full system, loaded the new ide-cd_mod driver, made sure there is _no_ CD in the drive and then ran glxgears in a window with composite extension enabled (as mentioned above, this is the quickest way I found to reproduce the kernel panic). It crashes after a few seconds. It does so every time. This is in the first log I will attach after writing this. For the second test I booted the full system, loaded the new ide-cd_mod driver, made sure there _is_ a CD in the drive, then ran glxgears for a bit, then ejected the CD (check for "Remove CD from CDROM" which I wrote to syslog with logger) and it crashed almost immediately. I haven't yet tried to reproduce this, but I saw it happen twice to me before. This is in the second log attached. After these two tests I booted again as previously but this time kept the CD in the drive and went for dinner. That's about 50 minutes ago now - glxgears is still running without a kernel panic. I never before took care whether there is a CD in the drive or not, but it seems to prevent the kernel panic from happening. Maybe my assumptions are all wrong - after all, I have no idea how to read those debugging messages. Thank you very much again for looking into this.
