Hi guys and Marius, (sorry for the cc but you did bring up the topic so I'm figuring that you probably know the most about this subject!) I am just in the process of figuring out which Sun bridge I will need for the Fire v480 server as a quote from Marius Strobl suggests this: [quote] FreeBSD currently crashes on older models of V480 when attempting to use an on-board NIC due to what appears to be a CPU bug which needs to be worked around. It appears to work fine on later V480 equipped with version 7 Schizo bridges (that's just an indicator and unlikely related to the problem) though, but FreeBSD 7.3 will be the first release (besides the current stable branches) to work with their changed firmware behavior. Linux doesn't seem to do any better in this regard: http://marc.info/?l=linux-sparc&m=122220796209509&w=2 http://lists.debian.org/debian-sparc/2009/12/msg00012.html Marius [quote] My supplier has given me an extract from the Sun handbook which doesn't seem to show version 7: A37 501-5819 501-6733 November 2001 <=501-5819-12: SCHIZO 2.2 >=501-5819-13: SCHIZO 2.5 August 2003 reworked 501-5819-12 SCHIZO 2.2 only available from Sun Services 501-6780 501-6790 December 2003 FAB 270-5819-06 SCHIZO 2.5 April 2004 FAB 270-5819-07 SCHIZO 2.5 or ELE 1.1+ A bit of Google'ing however got me to this: [quote] Version /Schizo/ Rev /7/ 2.5 6 2.4 5 2.3 4 2.2. Symptoms. Should the described issue occur, /Sun Fire/ 280R, /V480/, V880 and Netra 20 systems may encounter a FATAL *... *[/quote] From here: http://sunsolve.sun.com/search/document.do?assetkey=1-66-200502-1 also this: [quote] * FreeBSD has been adopted to the changed firmware of newer Sun Fire V480 (those equipped with version 7 Schizo bridges) and has been reported to now run fine on these. The necessary change will be part of 7.3-RELEASE. Unfortunately, using the on-board NICs in older models of Sun Fire V480 (at least those equipped with version 4 Schizo bridges) under FreeBSD still leads to the firmware issuing a FATAL RESET due to what appears to be a CPU bug, which needs to be worked around. [/quote] Taken from the Sparc64 part of this page: http://marc.info/?l=freebsd-hackers&m=126375029221240&w=2 What I can understand from all of this is that the version 7 is actually a revision 7.... so any of the bus versions listed above in the table will work as long as they are revision 7 or later? Is this the case, have I understood correctly?? Regards, Kaya
