asterisk users - Feb 2010 - Getting: Can't fix up channel from 5 to 7 because 7 is already in use, and pri_dchannel: Answer requested on channel 0/7 not in use on span 1

System have been working great for weeks, using an average 40 of 120
dahdi channels.

But today, I suddenly see scary things like this:

    -- Moving call from channel 5 to channel 7
[Feb 25 10:18:12] WARNING[17129]: chan_dahdi.c:10608
pri_fixup_principle: Can't fix up channel from 5 to 7 because 7 is

pri_fixup_principle: Whoa, there's no  owner, and we're having to fix
up channel 5 to channel 7

[Feb 25 10:21:44] WARNING[17129]: chan_dahdi.c:10661
pri_fixup_principle: Call specified, but not found?

What would be the reason for things like this to happen?

And are they really just warnings (as it says), or actual errors,
where something bad is happening to the actual calls, or calls not
acknowledged?

H?kon

Sometimes I get these in my kernel log:

[3763662.549761] __sdla_bus_read_4:888: wanpipe PCI Error: Illegal Register
read: 0x0040 = 0xFFFFFFFF
[4014422.079673] __sdla_bus_read_4:888: wanpipe PCI Error: Illegal Register
read: 0x0040 = 0xFFFFFFFF

Anyone who knows what this is about?
