Hey guys,
I’ve just got my new laptop, and have finally got Trios installed on it (YAY!).
I’ve hit a few issues with the kernel, and was going to log a bug report with debian, but I suspect that will show that packages from Trios are installed.
This raises a bigger question:
If I have a problem with a package from the debian repos, should I raise it with debian or yourselves?
Cheers,
It depends … if we can solve problem, you can submit a bug to us 
Joking aside … trios has a vanilla kernel from debian jessie repo, so it’s best for you to describe what is the problem with kernel.
@Dragan Thanks for the quick reply.
Have a new Dell XPS 13", and am getting the following

This causes intermittent wireless drop outs (interfaces stays up, and ip remains, but traffic drops in and out)
Also having issues with the synaptics touchpad, which “apparently” are fixed in later kernels…
@spOOn
It seems this is wifi driver bug, already submitted to debian
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=773676
Hmm, okies, Ill wait for someone from debian to catch this one.
On the synaptics issues, I see RH have patched it, and apparently is resolved in a later kernel:
https://bugzilla.redhat.com/show_bug.cgi?id=1188439
Got any recommendations on the way forward here? Being that the current debian kernel is significantly behind the kernel with the fixes included?
At trios, we decided to not touch kernel at all until jessie become stable…maybe some of the current bugs will be fixed untill then.
Hello @spOOn ,
You can always try current kernel from Debian experimental (3.19 now).
I’ve used it multiple times without any big hassle ( 3.17 currently running ), although it may cause problems here & there.
Usually some applications that have kernel modules/drivers may fail to rebuild them…
That ofc is for taking a relativelly small jump, like in this case 3.16 --> 3.19 ( going for 3.2 --> 3.19 on, eg. Wheezy would be a serious pain )
At any rate, it doesn’t cost you anything to give it a shot, except for some waiting*. If it’s more trouble than it’s wort, you still have original 3.16 to go back to. 
When it shows up, if you need help installing, ask here, or check this nice how-to:
http://anttdev.blogspot.com/2013/03/how-to-install-latest-upstream-kernel.html
Well, I guess it’s best to raise it with both of us.
However post here first, just in case it happens to be in one of our packages, or ones we’ve modified.
@spOOn
@Filip
Just to mention regarding recommendations for kernel versions…ZFS on Linux is officially supported only up to version 3.16.
Hi guys, thanks very much for the good advise
@Dragan thanks for that, but I’m not using ZFS anyways…
@Filip yeah, I noticed the kbuild package was missing so I’ve compiled and packaged myself, and the good news is my touchpad is now working correctly (YAY!).
Bad news is that this broadcom bcm4352 is no longer working…
I’ve tried the latest broadcom-sta-dkms from debian sid, as well as downloading the package directly from broadcom and compiling, and no luck so far.
I ever tried a couple of patches for this package floating around on the internet, which helped, but I seem to now be at a dead end (my limit

Any advice appreciated.
Cheers,
Did you try the “linux-latest” patch from Arch/AUR? Judging by the comments/forum it seems to be compiling correctly on 3.18/3.19 kernels with it…
https://aur.archlinux.org/packages/broadcom-wl/
https://bbs.archlinux.org/viewtopic.php?pid=1495005#p1495005
Hi guys,
Have fixed the broadcom-sta driver so that it actually works with 3.18 and 3.19
Happy to provide the fixed source if anyone is interested…
