Bug: segfault in "ffado-test Discover"
Suggestion:
The reporter acknowledges that prior to running ffado-test "there
already were problems with the Firewire connection". The crash is
associated with a bus reset. While bus resets should be handled
cleanly by FFADO, it is not always the case. In a properly
functioning system there should be no sporadic bus resets. Bus
resets normally occur when the bus topography changes (a device is
added or removed for example).
It seems that the system is experiencing frequent bus resets. This
most likely indicates a hardware fault. This could be in the audio
device, the firewire cable or the firewire card in the computer.
The first thing to try is a different firewire cable from a reputable
manufacturer. There were many dodgy firewire cables made, and bad
cables can give rise to all kinds of strange problems.
Another option is a firewire card which isn't up to the task of
managing the datastream associated with an audio interface. This is
unlikely to be the cause here though, since the fault is occurring
during device probing which isn't particularly taxing on the firewire
bus.
