Hello,

So that I have to wait 5 s for the disk to come up. I tried 3.4.15 and
3.6.3, both with the same result.

00:1f.2 SATA controller [0106]: Intel Corporation 7 Series Chipset
Family 6-port SATA Controller [AHCI mode] [8086:1e03] (rev 04)

Any ideas what is going on?

Anybody? I also tried 3.0, it's there too. And libahci.skip_host_reset=1
works around the issue.

FWIW, I had the same issue on an AMD chipset at the old job. It needs to
reset SATA link for some reason, probably BIOS programs it wrongly...
