After running jackd with L2 all night, the only repeated XRUN was this one:

ALSA /home/rlrevell/cvs/alsa/alsa-driver/alsa-kernel/core/pcm_lib.c:139: XRUN: pcmC0D2c
[<c01066a7>] dump_stack+0x17/0x20
[<de93d54b>] snd_pcm_period_elapsed+0x27b/0x3e0 [snd_pcm]
[<de979211>] snd_emu10k1_interrupt+0xd1/0x3c0 [snd_emu10k1]
[<c01078d7>] handle_IRQ_event+0x47/0x90
[<c0107e93>] do_IRQ+0xe3/0x1b0
[<c0106268>] common_interrupt+0x18/0x20
[<c0146771>] add_to_swap+0x21/0xc0
[<c0139446>] shrink_list+0x156/0x4b0
[<c01398ed>] shrink_cache+0x14d/0x370
[<c013a118>] shrink_zone+0xa8/0xf0
[<c013a4ee>] balance_pgdat+0x1be/0x220
[<c013a5f9>] kswapd+0xa9/0xb0
[<c0104395>] kernel_thread_helper+0x5/0x10

This produced a few ~2ms XRUNs. The shrink_zone -> shrink_cache -> shrink_list
is a recurring motif.

Is this addressed in M2?
