Bug#830300: bug in mdadm

[Любен Каравелов]

Hi,

The problem I am trying to solve is that my laptop (ASUS Zenbook UX301LAA) is using Intel RAID0 setup:

00:1f.2 RAID bus controller: Intel Corporation 82801 Mobile SATA Controller [RAID mode] (rev 04)

But it stopped working 5-6 months ago (3.3.2-5 was the last version that was working out of the box). My understanding is that for some reason mdadm is not recognizing the setup as being a IMSM RAID and I was forcing the RAID assembly to bypass this check with the envvars until this was also broken by the last mdadm update.

BTW, I also tried another workaround but it does not work also for me with the last debian mdadm package:
https://bbs.archlinux.org/viewtopic.php?id=202597

For the moment I downgraded the mdadm and put it on hold.

Any other suggestions are welcome.

Regards,
luben
