max number of devices in raid6 array

		Hello,

	I want to create an raid6 array and I see an limit of number of
devices : with 27 devices the array is created, and with 28 I've got
this error :
mdadm: invalid number of raid devices: 28

	I use kernel 2.6.30 (from backport) and mdadm - v2.6.7.2 - 14th
November 2008 on Debian Lenny.

	Is there a way to pass out this limit ?

	Thanks,

	David.
