Alphastation stopped booting with 2.4.10+

[Christian Groessler]

Hi,

2.4.9 worked fine, but starting with 2.4.10 my Alphastation 200
stopped booting. It simply halts immediately after being called by
aboot:

------------
aboot> 6
aboot: loading compressed boot/srm-vmlinux-2.4.10.gz...
aboot: zero-filling 147840 bytes at 0xfffffc0000a82520
aboot: starting kernel boot/srm-vmlinux-2.4.10.gz with arguments root=/dev/sda5 video=tga:font:SUN12x22,mode:1024x768-76 console=ttyS0

halted CPU 0

halt code = 5
HALT instruction executed
PC = fffffc00009b0cc0
>>>

I think the problem is the newly introduced opDEC_check, if I do the
following change 

------------

         */
        if (implver() == IMPLVER_EV4) {
-               opDEC_check();
+               /*opDEC_check();*/
        }
 }
------------

the computer boots OK.
I'm using SRM V7.0-9 and aboot 0.8 on an AlphaStation 200 4/100
