by Aramico

But, its all ok after replacing the DVD RW with common cd rom. can you help me here how to copy data from physical hardisk to a blank dvd drive ? whats the command ? Thanks all. Regards, Aramico

Andy> I think I somehow built the computer from Hell. Recall my dual Andy> Opteron box with SuSE 9.2 and 1 GB of memory. Bummers, I've been thinking about going the opteron route as well with a dual box like this. Thoughts off the top of my head: 1. Is the BIOS updated? 2. Can you tune/tweak the BIOS settings to more conservative values? 3. Try running kernel 2.6.14-rc5, there were various problems found and fixed with AMD stuff. 4. Try booting a UP kernel -or- Try booting an SMP kernel with 'nosmp' boot option. 5. Try booting with the 'noapic' option. 6. Boot with a serial console, log all output to another system. Try to do magic SysRq from that console when the system hangs. Andy> I removed every SATA device from my system, and now it doesn't Andy> hang as often, but it still hangs periodically. Hmm... this points to the problem not being SATA then. Can you disable the SATA chipset from the BIOS level as a test?

It would be good to know what type of lockups you're getting here. Does it lockup when the system is idle or in use? Andy> I am suspicious of the 2.6 kernel.

Not really, though you might have issues if you have binary modules for closed source drivers. I'd grab the 2.4.31 kernel and try it out. It should work fairly well on there, though you might have issues if you use udev for your devices. Someone else suggested a LiveCD, which I think is a good idea. If you can, trash one of your SATA disks and do a debian/ubuntu install using the 2.4 kernel and see what happens. We run Rackable Dual/Quad opterons at work with RHEL 3 and they just work. But we're only stressing them with CPU bound jobs, not with devices or graphics or audio or anything like that. Good luck! John

The distribution configs always work for me. They probably see the most testing, if you think about it. One other suggestion: have you checked to see if there are any BIOS updates? I've seen *very* strange problems of the random variety that are really BIOS bugs. If you're really serious about tracking this down, I'd start doing some stress testing to see if you can get a reliable reproducer. Without that, it's tough to address. Or, enable kexec/kdump. There's a quick blurb on it in fedora weekly news, but that's for fedora. -Jeff

Not specifically, but each of us has a computer that sometimes stops dead for no reason. I have always assumed that mine was due to some hardware that runs on the edge. Once or twice a crash seemed to happen exactly when I bumped the case. I moved it from my desk and set it on a shelf where it was never touched (well, hardly ever). It has been running as a firewall 24 hours per day for about a year with random crashes less common than power outages and thunderstorms. In the past few days it has crashed dozens of times, and sometimes takes two or three tries to re-boot. Maybe it doesn't like water dripping from the walls and soaking wet carpets. I just bought a bunch of parts and will attempt to build a computer not from Hell. > I am suspicious of the 2.6 kernel.

Do you have 'third party' modules? It should be no problem having two sets of modules installed, as long as the kernel version numbers are different, since each kernel looks for its modules in a directory with its own name on it. But the new kernel must have new powers. Does SuSE depend on the new stuff? -- Keith

System hang woes continue

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI gang, I think I somehow built the computer from Hell. Recall my dual Opteron box with SuSE 9.2 and 1 GB of memory. I removed every SATA device from my system, and now it doesn't hang as often, but it still hangs periodically. This time I got 10 days of uptime before it hung - a new world's record on this particular box. Strangely enough, I could demonstrate more uptime with the "old" SATA code than with libata - go figure. I am suspicious of the 2.6 kernel. We run dual Opteron servers at work with the 2.4 kernel series with no problems at all (on RedHat 7.3). I am wondering what would happen if I took SuSE 9.2 and replaced the 2.6 kernel with a 2.4 kernel. Am I asking for a heap of trouble? What specific issues would I encounter? I'm guessing that the kernel modules would be all fubar since I thought taht 2.4 and 2.6 did that quite differently. Perhaps I could bypass that with a monolithic kernel. I'm not sure what other problems I'd make for myself if I did this. Another thought - does somebody have a .config file for a Linux 2.6 kernel on an Opteron system that works really well?

I'm surprised I missed it initially. I'm not a Rommney fan, but I have to give him credit for trying to push this. It's a great initiative which will obviously be expensive to implement early on but will of course save hordes of dough for the state in the end. I don't think Galvin is playing politics here...too much, anyway. Like any administrator he is probably worried about big headaches it will likely cause to get this off the ground, but hopefully Rommney has a master plan to get it done as best as possible. -- Gary
