You may use Xenomai v2.5.2 now. Everything is fixed now. See the other 
messages of this thread.

OK. Please, verify first that you can boot µClinux without Xenomai on 
your board with the 2 extra hrtimer and hrclock peripherals.
There is no priority on IRQ with NIOS.
Please verify that you have correctly enabled all the right options 
under SOPC builder for hrtimer and hrclock.
Because we have flexibility in HW configuration with SoPC, we must be 
more careful.

For uCLinux configuration leave, do:
$ cd uClinux_dist
$ make menuconfig
In the menuconfig screens, verify that the following options are enabled:
Vendor/Product Selection --->
--- Select the Vendor you wish to target
Vendor (Altera) --->
--- Select the Product you wish to target
Altera Products (nios2) --->
Kernel/Library/Defaults Selection --->
--- Kernel is linux-2.6.x
Libc Version (None) --->
[*] Default all settings (lose changes)
[ ] Customize Kernel Settings
[ ] Customize Vendor/User Settings
[ ] Update Default Vendor Settings

and follow the doc from page 25 (keep all options by default).

According to errno.h, code -19  is ENODEV, please verify your timer 
configuration and respect naming convention.
