Avago controller support 256K max IO. max_sector_hw_kb should be 256. Anything like 1024 or 4096 is invalid. Once FW receive more than it can support, IO will be failed and print like " megasas: FW status 0x3" will dump on console from Driver. I will check how Driver behaves using 14.10 Kernel on non-PPC environment.

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.
