[Bug 1376661] [NEW] Strange behaviour of ahci driver (intel 82801 Mobile SATA Controller)
You have been subscribed to a public bug:
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:
