I mean can you mount it if you do it by hand, not via
fstab. I.e., call mount -t ubifs ...

UBIFS Crash with ubifs-v2.6.21-HEAD.tar

Hi all,

 I am using kernel 2.6.18. and i have backported from 2.6.21 to
2.6.18. when i add kernel command line parameter as ubi.mtd=exe
ubi.mtd=2 .

i got crash in core.c file in function int device_add(struct device
*dev). The reason for this i found is parent =
get_device(dev->parent); is null.

can any body suggest where dev->parent value gets assigned.

Regards
Naveen

Here you may find a way to mount UBIFS via kernel boot parameters:

Not sure, this is ancient kernel and I doubt anyone is interested
digging it. You may try luck at lkml though, but I fear you'll
have to dig this yourself.

Try adding:

ubi.mtd=0 root=ubi0_0 rootfstype=ubifs

to the kernel boot line.

[PATCH Resend] Remove 'SBC8240 Wind River' Device Driver Code

Hi,

Linux next tree(20090626) produced the following build error:

I remember reporting this back in April, when it was suggested to remove
the code as it is no more used:
http://lkml.org/lkml/2009/4/21/476,

I tried to gather some more info about this driver from the link
mentioned in Kconfig:
http://www.windriver.com/products/sbc8240/,
without much success.

The original author of this driver code has no problem, as she has
expressed by the following mail:
