Fail to mount ubifs

[Jon Ringle]

Hi,

I'm having problems with mounting ubifs. Flash is 32MB NOR (Intel
strata JS28F256P30T95).

Linux-2.6.31.11 with backport updates from
git://git.infradead.org/~dedekind/ubifs-v2.6.31.git

It fails to mount even if I truncate the volume with 'ubiupdatevol -t
/dev/ubi0_2'.

Thanks for your help.
Jon
