Hi all,
I have a machine running FreeBSD 5.4-RELEASE-p11 with a TE110P, Asterisk
1.2.4, libpri 1.2.1, zaptel 0.11 all installed from ports.
This machine had been running fine for almost 6 months with older
versions of those packages (asterisk 1.0.9, libpri 1.0.9, zaptel 0.10),
but since I upgraded, I've been having spontaneous reboots happening
only under load (no nightly reboots) every hour or so, depending on the
amount of calls.
A few days ago I ran to the datacenter to change hardware, and I changed
everything except for the Wildcard itself. What I left out in my rush
is that the digium was sharing IRQ with the onboard USB controller and
with the FireWire controller. No reboots happened in these days, but I
could see a lot of IRQ misses showing up in zttool, and the accuracy
measured by zttest was around 99,96 on average.
I had somebody show up and change the IRQ settings this morning, and so
far I've had two reboots in less than 3 hours. I see no IRQ misses,
though, and fax reception works smoothly (some lines lost here and
there, but it's pretty much acceptable).
To summarize:
Sharing IRQ:
- No reboots
- No faxes
- Lots of IRQ misses
- Low audio quality on calls
_NOT_ sharing IRQ:
- Good audio quality
- Faxes get through (using spandsp)
- No IRQ misses
- SPONTANEOUS REBOOTS
I think this problem refers to fast interrupts/sleep mutexes issue
discovered by Konstantin Prokazoff.
Try latest svn snapshot from
http://www.voip-info.org/tiki-index.php?page=FreeBSD+zaptel, i've commited
possible fix and will appreciate any testing results. Thanks!
