[Kernel-packages] [Bug 1392021] Comment bridged from LTC Bugzilla
--- Comment From christian.r...@de.ibm.com 2014-12-03 16:56 EDT--- Successfully tested the 3.16.0-26-generic packages of which the extended package has the right (2.0.25) version of the genwqe_card module in. I was able to rmmod, modprobe and on reboot the system successfully loaded the genwqe device driver. I could run compression/decompression workload successfully. That said, I had to manually install the .deb packages found on https://launchpad.net/~canonical-kernel- team/+archive/ubuntu/ppa/+build/6612025 as 'apt' was not showing the 3.16.0-26 kernel updates from the 'trusty-proposed' repository for my vivid 15.04 system. crund@tulg3:~$ uname -a Linux tulg3 3.16.0-26-generic #35-Ubuntu SMP Tue Dec 2 16:38:01 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux crund@tulg3:~$ modinfo genwqe_card filename: /lib/modules/3.16.0-26-generic/kernel/drivers/misc/genwqe/genwqe_card.ko -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1392021 Title: Ubuntu 15.04 [genwqe_start] err: could not setup servicelayer Status in linux package in Ubuntu: Triaged Status in linux source package in Utopic: Fix Committed Status in linux source package in Vivid: Triaged Bug description: [Impact] The IBM GenWQE Accelerator Adapter does not work correctly in the latest 3.16 kernel.

Ubuntu picked and unfortunate intermediate version of the driver which had broken irq registration. This was fixed later by Sebastian Ott and Kleber and I added on top of that some more patches which did cleanups and more importantly added System p specific recovery features e.g. like EEH handlers and a method to reload the bitstream for p. Therefore it would be great if someone could have the Ubuntu folks pickup the latest version from Kernel.org. I know that Greg KH has a good version of the code in his tree. We need to check if that has made it yet into Linux version (both should be the same). == Comment: #3 - Frank Haverkamp - 2014-11-12 07:58:03 == Christian has checked the linux.git version of the genwqe_card driver compiled against his Ubuntu kernel and found it working.
