	Hello,

	I have seen same freezes on Blade 2000 (2 * US III+/900 Cu), on U5 (US 
IIi/440), but not on a server that run with four US IIIi and not on a 
T1000 (sun4v/US T1). I have tested 3.2 debian kernels and official ones 
and both hang. I suppose there is another strange bug with special MMU. 
2.6.32 is stable but on sparc64, 3.2 is not. I have not tested newer 
kernels.

	Regards,
