Subject: [sound] mpd loops on current -next
Date: Sat, 06 Jun 2009 17:46:50 +0200	[thread overview]
Message-ID: <4A2A8F6A.80705@gmail.com> (raw)

Hi,

I found a regression in current -next caused by
c44941e05900fe85f6091456f9e313b446a97ae9
(PCM midlevel: Do not update hw_ptr_jiffies when hw_ptr is not changed)

When mpd is playing, it loops with a pattern such as:
16:05:02.762544 ioctl(14, 0x4122, 0x3)  = 0
16:05:02.762565 ioctl(14, 0x4122, 0)    = 0
16:05:02.762587 ioctl(14, 0x4122, 0x1)  = 0
16:05:02.762609 ioctl(14, 0x4122, 0x3)  = 0
16:05:02.762630 ioctl(14, 0x4122, 0)    = 0
16:05:02.762652 ioctl(14, 0x4122, 0)    = 0
16:05:02.762674 poll([{fd=13, events=POLLIN|POLLERR|POLLNVAL}], 1, -1) =
1 ([{fd=13, revents=POLLIN}])
16:05:02.762698 ioctl(14, 0x4122, 0x3)  = 0
16:05:02.762720 ioctl(14, 0x4122, 0)    = 0
16:05:02.762742 ioctl(14, 0x4122, 0x1)  = 0
16:05:02.762765 ioctl(14, 0x4122, 0x3)  = 0
16:05:02.762787 ioctl(14, 0x4122, 0)    = 0
16:05:02.762809 ioctl(14, 0x4122, 0)    = 0

Reverting the patch makes the problem disappear.
