Actually, I got (IIRC) the same error when I booted up 2.6.30 vanilla, using the same config (as much as possible) as my currently in-production 2.6.25-gentoo-r2 (SMP) on UltraSparc Enterprise2 don't have a test machine to play with, and this is at a remote facility- break on console isn't enough to get back to PROM after this, for some reason, so I have to drive out to power-cycle. > -----Original Message----- > From: sparclinux-owner@xxxxxxxxxxxxxxx > [mailto:sparclinux-owner@xxxxxxxxxxxxxxx] On Behalf Of > Alexander Beregalov > Sent: Monday, June 29, 2009 7:30 AM > To: sparclinux; David Miller > Subject: 2.6.31-rc1: sparc T2: Fast Data Access MMU Miss > > Hi David > > This is the first time I try to boot Linux on that system, > perhaps config is wrong (attached). > Kernel is 2.6.31-rc1-00195-g5298976. > Gentoo LiveCD kernel 2.6.24 works fine. > > > SPARC Enterprise T5120, No Keyboard > Copyright 2008 Sun Microsystems, Inc.
