[luv-main] Default grub options for RHEL6 ?
Hi folks, Anyone know what the default grub options you get on a RHEL6 box are ? Do they include acpi=off ? If so, is that conditional upon something that Anaconda/kickstart detects ? Or something that must be explicitly selected ? (Got a friend in the US who has found a box with acpi=off set, which is bad for NUMA hardware if the kernel is relying on ACPI to get that info). cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file. Do not panic. For more info see: http://en.wikipedia.org/wiki/OpenPGP

None of my OL6 boxes have acpi=off in their grub options, so it's not a default that I can see. However, I can't comment on whether this is triggered by anaconda under some condition not available on any of my installs. I checked my bare-metal installs, as well as Xen HVM/PVM guests. Cheers, Avi

Can also confirm that none of my RHEL6 default installs, bare–metal or VMware, have acpi=off -- Joel Shea <jwshea@gmail.com>

Thanks Joel and Avi - I suspect my friend is looking at a performance problem caused by the hardware owner, not RHEL.. ;-) cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC
