Package: linux-2.6
Severity: normal
Hi!
At least 2.6.30-2 ships with the new firewire stack (Juju). This stack
is nearing feature-completion, however, there's at least one exception:
FFADO, the userland driver for firewire audio cards, can only be used
with the old stack.
This is a known problem, it's mentioned in the 1394wiki:
http://ieee1394.wiki.kernel.org/index.php/Juju_Migration#Compatibility_and_stability
There's also an FFADO ticket about it:
http://subversion.ffado.org/ticket/78
We now have the case that FFADO has entered Debian Unstable, but the
kernel isn't capable of running it. ;)
I guess this is somewhat related to #435062. Though the versions don't
match, but the bugs could probably be merged.
There's a Google Summer of Code project trying to write an in-kernel
driver for firewire audio, but currently, there are no results. It would
take some months to complete it.
Long story short: can you enable both stacks? I guess blacklisting the
old stack would be ok, it's mentioned here:
http://ieee1394.wiki.kernel.org/index.php/Juju_Migration#Module_auto-loading
I don't know if debconf is acceptable for a kernel package, so it could
ask which stack to use and create /etc/modprobe.d/ according to the
user's reply.
I could also tweak such a file in the FFADO package, so the kernel can
default to the new stack, and only the presence of FFADO enables the old
stack after informing the user.
TIA,
Cheerio
