Description of problem: An issue has been encountered where a DL380 G7 server may not display any output via the rear side VGA port when running rhel6.2 64-bit with rt31.66 and rt31.75 kernel, yet the all pors will work fine with X-window sometimes. This issue was not encountered in rhel6.2 with non rt kernel on the tests. However, same issue happended on SLES (SUSE Linux Enterprise Server) 11 SP1 64-bit. Solution not known. Version-Release number of selected component (if applicable): kernel-rt-2.6.33.9-rt31.66.el6rt.x86_64 kernel-rt-debug-2.6.33.9-rt31.66.el6rt.x86_64 kernel-rt-debug-devel-2.6.33.9-rt31.66.el6rt.x86_64 kernel-rt-devel-2.6.33.9-rt31.66.el6rt.x86_64 kernel-rt-firmware-2.6.33.9-rt31.66.el6rt.noarch kernel-rt-trace-2.6.33.9-rt31.66.el6rt.x86_64 kernel-rt-trace-devel-2.6.33.9-rt31.66.el6rt.x86_64 kernel-rt-vanilla-2.6.33.9-rt31.66.el6rt.x86_64 kernel-rt-vanilla-devel-2.6.33.9-rt31.66.el6rt.x86_64 How reproducible: always Steps to Reproduce: 1. 2. 3. Actual results: rhel6.2 -------------------------------------------------------------------- X window in use Xwindow not in use front VGA port ok ok Rear VGA port ok ok rt31.66 -------------------------------------------------------------------- X window in use Xwindow not in use front VGA port ok not work Rear VGA port ok not work rt31.75 -------------------------------------------------------------------- X window in use Xwindow not in use front VGA port ok ok Rear VGA port ok not work Expected results: Additional info:
kernel-rt-2.6.33.9-rt31.66 is an older RT kernel. As an additional data point, can you please try our most recent kernel, kernel-rt-3.0.30-rt50.62.el6rt?
oooooooops, sorry for late reply, i don't know why i am not able to see your comment from my ticket... It's a production server ,so very unlikely they could upgrade their kernel .. But I will recommend them anyway.. Thanks -mjin
This issue has not been updated in a while and is using an older, unsupported kernel. In addition, the corresponding customer Case 00672608 has been closed. This BZ is being closed WONTFIX. If you believe this is still an issue on our most recent MRG-2.5 3.10 Realtime kernel, please file a new issue for further investigation.
