[2.5.69] can't open root device on md1?

[Julien Oster]

Hello,

after some success on other machines, I decided to boot 2.5.69 on my
main workstation.

The filesystems of that workstation are completely SoftRAID Level 1
devices, except for one which is a Level 0.

However, while booting up, the kernel refuses to mount the root
filesystem. The arrays and everything seems initialized correctly, there
are a lot of messages from the md driver as there were in 2.4.21-rc2. No
errors.

However, the 2.5.69 dies with

VFS: unable to access root device "901" or "/dev/md1"

(I haven't attached any serial console so I'm doing cut'n'paste from my
mind)

Any idea why this happens? Have the device numbers changed?

Regards,
Julien
