So assuming the the value max_sectors_kb is changed to 1024 (with the 2048 kernel command line) that means we need to figure out what the correct value is for the Avago controller. Currently it's set as 4096 in the kernel according to C#28. It appears 1024 works, but if we get the actual value that's better for performance.
What is the actual hardware limitation of the Avago controller? If the limit is really 4096 that would imply that it's just broken on PPC64LE which could be another driver or a firmware bug that was only revealed when the default limit was changed from 1024. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475166 Title: Ubuntu 15.04 Install Error with Avago Controller To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475166/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
