>i have released the -V0 Real-Time Preemption patch, which can be >downloaded from: > > http://redhat.com/~mingo/realtime-preempt/ Actually, I picked up -V0.1 since that was available when I started this morning and of course -V0.2 came out while I was building....
The kernel I built does not even make it to single user mode unless I disable selinux.
First try had console messages stop after the message INIT: version 2.85 booting but the Alt-Sysrq keys do work. Alt-Sysrq-L shows...
Pid: 5, comm: ksoftirqd/1 EIP: 0060:[<c011d808>] CPU:1 EIP is at smp_processor_id+0x28/0xc0 (registers and stack trace...) preempt count: 00010002 ...
Pid: 266, comm: IRQ 1 EIP: 0060:[<c0115b70>] CPU:0 EIP is at nmi_show_all_regs+0xd0/0x120 (registers and stack trace...) preempt count: 00010002 ...
If I repeat this a few times, the first process changed to "hotplug". Repeating Alt-Sysrq-L will eventually gets stuck and requires a hardware reset.
Second try - the INIT message was incomplete, stopping at INIT: plus the Alt-Sysrq keys not working at all.
Third try - added selinux=0 to the boot parameters. Made it single user mode w/o any errors. Using telinit 3 got me a few BUG messages related to modprobe and sleeping from an invalid context. From what I read in other messages, you may have already fixed that so I will be building -V0.2 shortly.
I also got the atomic counter underflow (qdisc_destroy) message.
Let me know if you need the system log, it appears to have captured the messages if you need them.
