Mark, I realize you have had a few BIOS/hardware issues with this platform. Just making sure if the BIOS upgrades have helped you to resolve this issue. I guess I am having a hard time trying to reproduce this issue. Thanks, Shyam Well, there's a good reason for that. You probably didn't have a system with a C410x attached. Our C410x has two nVidia M2070's in slots 0 and 15 (if I recall correctly). Having this attached to the system was causing the hang. So it seems that potentially one of the KMS drivers was doing something "bad" and causing the system to hang. I was able to workaround the issue by either installing the base operating system without the C410x attached initially or just using the basic video driver. I'm not sure how much it is worth even trying to figure this out other than it shouldn't cause the kernel to freeze in the first place. But it is an odd hardware configuration to some extent.

I guess the only option is to use the basic video driver(vesa) to install. The nouveau driver driver does not support this card. You might talk to Dell support and they could point you to the nvidia binary drivers for this card after install. Also, here is a relevant link about RH support on this card. https://access.redhat.com/kb/docs/DOC-19565.pdf Since RHEL 6.2 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. Can we get a full 'lspci -vnn' listing from this machine? The ASPEED chips do not have kernel modesetting support in RHEL6. So to the extent that 'nomodeset' solves your problems it's because it's preventing the nouveau driver from binding to the GPGPU board. There's no reason why the nouveau driver should have that kind of problem, as far as I know, so ideally we'd fix nouveau so this just isn't an issue. Reassigning to nouveau.

Any update on this with a later RHEL release? |
