Hello All!

I am install Debian/potato on AS 1000A and have some problems 
with reboot or shutdown system. When i say "shutdown -h" or 
"shutdown -r" system normally down, but not out to SRM.
Print : 

halted CPU0
halt code = 5
HALT instruction executed
PC=fffffc0000310040

and start scrolling messge :

System Machine Check Through
Vector 00000660 logout frame address 0x6060 code 0x211
IPRs:

Any ideas?

Debian/potato
kernel version 2.2.15

Alexey.
