Hi,
i found the time to build and boot into 2.6.16-rt17 and i got a BUG:
softirq-hrtmono/9[CPU#0]: BUG in check_monotonic_clock at kernel/time/timeofday. c:162 [<b0103ec5>] show_trace+0x25/0x30 (20) [<b0103ef3>] dump_stack+0x23/0x30 (20) [<b011840b>] __WARN_ON+0x6b/0xb0 (40) [<b013ca39>] check_monotonic_clock+0x119/0x130 (52) [<b013ddca>] __get_monotonic_clock+0xaa/0xc0 (60) [<b013dfe1>] get_monotonic_clock+0x21/0x50 (32) [<b011bca8>] it_real_fn+0x58/0xa0 (48) [<b0130f34>] run_hrtimer_softirq+0xc4/0x270 (60) [<b011de74>] ksoftirqd+0x104/0x1c0 (48) [<b012d4cc>] kthread+0xdc/0xe0 (48) [<b0100e55>] kernel_thread_helper+0x5/0x10 (268615708) --------------------------- | preempt count: 00000001 ] | 1-level deep critical section nesting: ---------------------------------------- ..

Besides the BUG i also am not able to run jackd with a periodsize of 16 frames reliably (xruns and a pretty big cpu load of around 30%). I suppose this might be due to the tracing overhead though (as preempt_max_latency shows a value of 34 and 16 frames at 48khz is in the 0.3ms range). Will rebuild w/o the tracing/debug stuff, to see how it performs then.
