Title: Strange behaviour of ahci driver (intel 82801 Mobile SATA Controller) Status in “linux” package in Ubuntu: New Bug description: Hi, I have a MSI GS60E Ghost Pro laptop. It is quite complex: 2 SSD in raid 0 (intel Raid) 1 HDD standard SATA 2 Gpus (intel and nvidia) I was trying to upgrade my trusty to utopic. On trusty if I remember well there was no way to have a functionnal intel raid disks. I had to delete the raid an go to 2 separate disks to take advantage of the SSD (involved reinstalling secondary OS used for gaming). Legacy boot: On utopic, I can now use it but the name of the device is still strange (don't know if it is expected, but on other scsi harware I had I always had standard names /dev/sdx...): /dev/mapper/isw_ihbcddegh_SSD, where SSD is the name given at raid creation of the volume. Despite of this device I still have access to bare device /dev/sda, /dev/sdb, with the added bonus of being able to destroy the raid on it if we let the default /dev/sda for grub install of utopic desktop (destroyed at the end of install). At install time we see /dev/mapper/isw_.... /dev/sda /dev/sdb and /dev/sdc, but it is readable on legacy installer even if not ideal. UEFI boot: If we boot on UEFI, it is more complex, as grub is not able to find the windows bootmanager for unknown reason (maybe not related). Don't know if I need to put it somewhere else, but at the install selection of disks and partitions, it is also a bit confusing as it show two devices for the raid /dev/mapper/isw_.... each with the copy of the partitions (split the raid) plus bare devices, /dev/sda, /dev/sdb. I don't remember, if I saw partitions on the bare devices equaly. I can make some undestructive tests for you (had hard time at making a working install on this machine). If really needed, I can switch to work on an other laptop, and go for destructive tests. You can find some hardware infos about the config there, setup, etc: http://paste.ubuntu.com/8478288/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1376661/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
