[asterisk-users] 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

[Håkon Nessjøen]

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?
