I hope I'm not stepping on toes reopening this. I wasn't able to find guidelines about already closed reports.
Using the linux-rt 2.6.27-3.8 released yesterday I still have at least some of the issues listed in the above comment by Luke Yelavich (https://bugs.launchpad.net/ubuntu/+source/linux- rt/+bug/281276/comments/6). Only one CPU is used and shutdown/restart do not work. Perhaps of note is that the rt variant does not set CONFIG_NR_CPU which is set to 64 in 2.6.27-7-generic and 8 in the old 2.6.24-21-rt and also does not set CONFIG_SMP which set to y on the others. After booting 2.6.27-3-rt dmesg contains this line: [ 0.000000] WARNING: NR_CPUS limit of 1 reached. Processor ignored. Compared to booting the non-rt 2.6.27-7-generic: [ 0.000000] SMP: Allowing 2 CPUs, 0 hotplug CPUs [ 0.000000] PERCPU: Allocating 64928 bytes of per cpu data [ 0.000000] NR_CPUS: 64, nr_cpu_ids: 2, nr_node_ids 1 ** Changed in: linux-rt (Ubuntu) Status: Fix Released => Confirmed -- Upgrade linux-rt to 2.6.27 https://bugs.launchpad.net/bugs/281276 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
