Bug#521717: zaptel-source: "FXO PCI Master abort" while network/disk/cpu usage is high

Package: zaptel-source
Version: 1:1.4.11~dfsg-3
Severity: important

I have a X100P clone card using the wcfxo module. It doesn't share an
IRQ with any other driver. When I transfer files on the gigabit
connection (so that CPU, disk and network usage all becomes high), wcfxo
generate *tons* of these error message and syslogd takes a lot of CPU,
slowing my network transfer to almost 0. It takes less than a minute
of network transfer so that this bug appears. I did not notice this
problem before because I had slow 10GiB IDE drives (and so not a lot of
free space to make big transfers). Now I upgraded to 250GiB SATA
drives (raid1).

[28309.306467] FXO PCI Master abort

I get so much of these messages that the computer becomes unusable
until I remove the wcfxo module. I tried with and without asterisk
running.

My network card (eth1) use the skge driver and my sata controller
sata_sil if it can help.
