Hi Adrian,

I tried some different versions from
git://git.infradead.org/~dedekind/ubifs-v2.6.27.git
and the problem is caused by commit " UBIFS: fix 64-bit divisions in debug
print " 
9d016dc4b3006ef3493b21442394028614e26da5 :

dbg_io("set timer for jhead %d, %llu millisecs", wbuf->jhead,
-       ktime_to_ns(wbuf->hardlimit)/USEC_PER_SEC);
-       hrtimer_start(&wbuf->timer, wbuf->hardlimit, HRTIMER_MODE_REL);
+       div_u64(ktime_to_ns(wbuf->hardlimit), USEC_PER_SEC)); 
}

As you can see the timer is no longer started. Could you please fix this ?

Thanks,

Ronny Dierckx
