All that patch appears to do is to remove an artificial limit for all devices to 1024. I haven't been able to reproduce the option reset on my systems, so here is what I would try:
Try setting the controller option and see if that sticks [1]: rmmod megaraid_sas modprobe megaraid_sas max_sectors=2048 It may also be possible to do this while booting as a kernel command option like: megaraid_sas.max_sectors=2048 (2048 does actually mean 1024 for the other options). Otherwise, I'd recommend switching to a Live CD and see if the option works there. If not, a last option would be to try using sysfs on the livecd to see if that will help ensure it: sudo add-apt-repository universe sudo apt update edit /etc/sysfs.ctl adding block/xxx/queue/max_sectors_kb = 1024 sudo apt install sysfsutils sudo service sysfsutils restart [1] http://fendertech.blogspot.com/2013/04/how-to-increase-maxsectorskb- for.html -- 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/1475166 Title: Ubuntu 15.04 Install Error with Avago Controller Status in linux package in Ubuntu: Triaged Bug description: Hello Canonical Team We are running to an issue installing ubuntu PPC64LE 15.04 full blown image on our servers (with RAID controller). Installation hangs around 70% of progress. An important part of our configuration is Avago RAID controller: 9361-8i Firmware version we used is 4.300.00-4429, and the package is 24.10.0-0002. IMPORTANT: It has to be noted that with same hardware configuration 14.10 full blown image installs fine. Dmesg logs are attached: Looking at dmesg logs point out that: LSI (avago) driver loads fine During further interaction with raid volume during the installation process, firmware errors are seen [ 196.991417] megasas: FW status 0x3 [ 196.999376] megasas: FW status 0x3 [ 197.007376] megasas: FW status 0x3 Further down the process I/O errors are thrown [ 217.438664] Buffer I/O error on device sda2, logical block 22052864 [ 217.438671] Buffer I/O error on device sda2, logical block 22052865 [ 217.438678] Buffer I/O error on device sda2, logical block 22052866 [ 217.438686] Buffer I/O error on device sda2, logical block 22052867 Full dmesg log is attached. Snippet is pasted below highlighting: It can be noted that there’s a Mellanox Connectx 3 pro card with some test Firmware on our setup. We can Ignore any diagnostic messages from that card in dmesg logs for the purpose of this bug.
