Re: [Bug 1592566] Re: can't write to a BTRFS disk with my powermac

[elvisplatini]

I installed Lubuntu a month ago, and I first selected BTRFS for the root 
filesystem, as on my amd64 machines. It didn't work so I choose ext4 for the 
root file system.
 
 Last week, when I first tried tu use my BTRFS fomated external drive, the 
kernel was in version 4.4.0-22. I couldn't write to it, as I can't now with 
version 4.4.0.24.
 
ppc64 kernels are not available on 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7-rc3-yakkety/. I will try to 
compile it from sources, and let you know if it works.
 
Thanks a lot for your help!

[Bug 1592566] Re: can't write to a BTRFS disk with my powermac

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.7-rc1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.
