I'd be interested in seeing a kdb or ksymoops backtrace if you
can provide one.  quotaon at startup is always ignored by XFS -
enabling quota is a mount time operation for XFS filesystems, so
this is likely to be a problem in the interaction between the
quotactl system call (takes a device special file as its second
argument) with Q_QUOTAON and devfs; and unrelated to XFS.

If you only have XFS filesystems using quota (and no ext2/other
filesystems using quota), you can safely remove the "quotaon -a"
from your startup scripts (thats really not a very nice solution
though...)

Jan, any chance you've come across this one before?  I don't
remember there being anything new/changed in 2.4.6 in the quota
subsystem, so seems odd that this would suddenly start to fail.

cheers.
