Hello,

I have applied the patch sent today, but the kernel don't find my root

Thank you very much,

Hello,

same result with vanilla with just this devfs patch:

Isn't that the right fix for fs/devfs/base.c ?

Thank you very much,

I had the same problem with sym53c8xxx_2 when devfs was configured into
the kernel (but not mounted). Then I made a kernel with devfs disabled and
now this boots (and seems to work).

Hello,

well, I "need" devfs and it is mounted... I really don't want to create
all the devices I use... At least now I know where does the prolem come
from ;-)

Thank you very much,

Here's a patch you can try out, I already posted this to linux-scsi
as a fix for /proc/scsi not showing up, I'll make sure James or
someone pushes it to Linus' tree. I don't use devfs.

This is against linus bk but should apply fine against 2.5.48.
