Re: Ultra-5 freezing
hi thank you all for the responses. sounds like i need to try older 2.6 kernel... hopefully can do this with apt-get because i dont want to reinstall OS.

Over the last few months I've experimented with Wheezy from CD or local netboot, and have found it unusable: the developers urgently need to check that it works ab initio, rather than relying on "apt-get upgrade" or whatever. We've reverted to Solaris on a number of systems, and I'm working on contingency plans to move off SPARC entirely. Apropos console cables: frankly, the serial console is one of the few remaining strong points of Sun systems. On systems which all have RJ45, you need a flat twist: i.e. 1-8, 2-7, 3-6 and so on; note that this is not the standard twisted Ethernet cable. To connect a machine with RJ45 to a PC, it's the same cable as a Cisco console port so refer to pinouts.ru. To connect a machine with an RJ45 to another Sun, you might need an additional twist or a null modem- check that. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- To UNSUBSCRIBE, email to debian-sparc-requ...@lists.debian.org with a subject of "unsubscribe".

Hello, scar a écrit : hi i have an Ultra-5 which has been housed in a datacenter for several years. It used to be running SunOS 5.9 and i didn't experience any problems with it. As that OS became obsolete, I installed Wheezy on the box not too long ago but now am experiencing hard freezes with no info in the system log as to what is happening. how can i troubleshoot? is it a software/OS/kernel issue? i did a barebones installation, not selecting any "roles" for the computer and have installed all software as needed (mainly openssh server), so it is a very slim installation. is it a recent hardware failure? how can i test RAM and other hardware, for example? You can use diag_switch? = true and diag_level = max (with a null modem serial line). You can also use SunVTS from Solaris. I have some trouble with all my U5 memory modules (until I use compatibles modules, not Sun branded ones). And UltraSPARC IIi/440 MHz seems to be fragile.
