Nothing works for me so far. THey both fail the same way. It's not in the photo but all the way through the boot the kernel calls the hard drives /dev/hda so I'm assuming that's correct in fstab. The kernel is 2.6.34-gentoo-r2 and the kernel config file is attached. ext3 is built into the kernel so that shouldn't be a problem. I built the kernel using the older 2.6.31 kernel config I saved. As a _hardware_ test I reinstalled the old OS X that came with the machine and it boots fine. I blew it away and installed Ubuntu 10.04 for the PPC and it boots fine, but Ubuntu uses and initrc which I've never used before with Gentoo. (And why on this machine as the hardware is fixed has kernel drivers.) I'm a long time Gentoo user. The main Gentoo install seems to work fine on this machine. As best I can tell it's only the yaboot stuff not booting that's holding me up from using this little machine again. Can anyone see what I've done wrong?

I'll reboot in a minute and check if it helped. (OK - I rebooted and it didn't fix anything unfortunately. Too bad. Thanks for the idea though.) I was wondering if this was one of those things where device names were changing. They were hda all through the install, which is different from the Install Guide. I've tried to adjust my yaboot.conf file accordingly but maybe it cannot find the disk at that point because the name changed or something. I cannot see anything in the boot screen to indicate that but I suppose it's possible. While I'm here in the chroot I decided to poke around a bit.

They offered to take my machine down and do a memory test which they said would take a number of hours. Is a memory test likely to help? Did you suggest reseating or replacing RAM modules as opposed to a memory test because it will result in less downtime? I suspect that your hosting provider are offering you this memory test because they don't want to go swapping out memory modules willy-nilly. How do they know that the problem is really memory, and not your operating system? If they take all this RAM out and put new RAM in, what do they do with the old RAM? They don't know if it's good or bad, so are they expected to just slap it in a server belonging to another customer, and stitch him up? A memory test is likely to identify bad RAM, if it is bad, so you should proceed with this. This is likely the best route to solving the problem. I think that ideally, for you, they would move the system image onto a different known-good server with the same configuration. Then you cannot complain if the same problems start occurring again. If the problem is genuinely hardware then they won't. And the hosting provider is free to run diagnostics on your old machine. But realistically, the memory test is likely to show up a bad RAM module, you'll get it replaced and be up and running within a few hours. Why would you refuse? If your system needed a guaranteed uptime you'd perhaps have to pay for a higher level of service than the fees you're paying at present. I run memory tests overnight. If a module is seriously borked then it will fail earlier. Reseating/replacing takes a few minutes, instead of hours. If they have spare machines (for dev't or testing) they can fit the memory module(s) there and test them exhaustively, before they put the good ones back into a customer's machine. Thanks Mick and Stroller. I'll see if they'll go for this. You're welcome. Bear in mind though that a lot of hosters are just glorified resellers with an account in a bigger data centre. In many cases they do not even have physical access to the machines. Only the data centre techies do and they may be less willing to oblige and break procedure or routine, just because one end user out of hundreds/thousands complained about some memory errors.

It's something to do with the TTL that the driver uses and I'm not sure that this is a parameter that you can see listed under modinfo. I believe it is hard coded. I'm on the latest hardened-sources kernel so I'll wait it out. In the meantime I've plugged in a USB wireless NIC and it's working fine. Thank you for your help.

Neither.
It's because one frequently wants to see the start or end of a file and much
less seldom something in the middle. When that is what you want, there are all

grep -{ABC} is the usual tool for that

Here is the only clue I see in dmesg: No probe response from AP a1:b2:c3:d4:e5:f6 after 500ms, disconnecting. Any ideas? Try a later kernel which would have a more up to date driver. Last time I had this problem it was corrected by unmasking and using a newer kernel. It's something to do with the TTL that the driver uses and I'm not sure that this is a parameter that you can see listed under modinfo. I believe it is hard coded. I'm on the latest hardened-sources kernel so I'll wait it out. In the meantime I've plugged in a USB wireless NIC and it's working fine. Thank you for your help. I'm on 2.6.34-gentoo-r6 and the b43 driver works fine here, but only a few kernels back it was exhibiting the same symptoms like yours. Some users have mentioned that if you use WPA/WPA2 encryption the symptoms are surprisingly less frequent! So until a more up to date kernel shows up you may want to look into experimenting with wpa_supplicant. I'm actually using the same kernel version, for me it's 2.6.34-hardened-r6. I've tried softmode with the same results. I'm using wicd and WPA2, and I tried wpa_supplicant when I first started having the problem with the same results. Thanks for your help. I'm sure it will be fixed up soon. Probably already fixed in newer kernel versions. - Grant
Re: [gentoo-user] machine check exception errors
I'm getting a lot of machine check exception errors in dmesg on my hosted server. Running mcelog I get: ... They offered to take my machine down and do a memory test which they said would take a number of hours. Is a memory test likely to help? Did you suggest reseating or replacing RAM modules as opposed to a memory test because it will result in less downtime? I suspect that your hosting provider are offering you this memory test because they don't want to go swapping out memory modules willy-nilly. How do they know that the problem is really memory, and not your operating system? If they take all this RAM out and put new RAM in, what do they do with the old RAM? They don't know if it's good or bad, so are they expected to just slap it in a server belonging to another customer, and stitch him up? A memory test is likely to identify bad RAM, if it is bad, so you should proceed with this. This is likely the best route to solving the problem. I think that ideally, for you, they would move the system image onto a different known-good server with the same configuration. Then you cannot complain if the same problems start occurring again. If the problem is genuinely hardware then they won't. And the hosting provider is free to run diagnostics on your old machine. But realistically, the memory test is likely to show up a bad RAM module, you'll get it replaced and be up and running within a few hours. Why would you refuse? If your system needed a guaranteed uptime you'd perhaps have to pay for a higher level of service than the fees you're paying at present. I run memory tests overnight. If a module is seriously borked then it will fail earlier. Reseating/replacing takes a few minutes, instead of hours. If they have spare machines (for dev't or testing) they can fit the memory module(s) there and test them exhaustively, before they put the good ones back into a customer's machine. Thanks Mick and Stroller. I'll see if they'll go for this. You're welcome. Bear in mind though that a lot of hosters are just glorified resellers with an account in a bigger data centre. In many cases they do not even have physical access to the machines. Only the data centre techies do and they may be less willing to oblige and break procedure or routine, just because one end user out of hundreds/thousands complained about some memory errors. Thanks Mick. My host is big with multiple data centers of their own. They did exactly as I asked and I'm running on new RAM. There was a problem bringing my system back online and the cause was purported to be an unseated ethernet cable. I handed over my root password as I was requested to do, and then started to get paranoid. I suppose I shouldn't though because with physical access to my machine they pretty much have full access anyway, right? - Grant
[gentoo-user] Checking an HD for problems
I just switched to a new WD Caviar Black hard drive (really fast and quiet!) and I noticed some errors when I was cp -ax'ing everything from my old drive to the new drive which were accompanied by loud clicks. Is there a way to do a comprehensive test/check of the old drive to see if it has any problems? - Grant

As a quick test, if the old drive has S.M.A.R.T. is to read the data held in the drive to tell you if the on-board controller is seeing problems. Hope this helps, Mark

Assuming that it's the old drive that is knackered, and if you're not certain that all important data has been copied correctly, then use GNU ddrescue (there is more than one dd_rescue, and GNU's is the best one) to do a bitwise clone of the data. Follow the examples in the manual to do multiple passes - the first pass will get most of the data from good sectors, subsequent passes will make repeated attempts at the bad sectors. Stroller.

Funny, though, the replacement drives I've received under warranty work spectacularly well. Just luck? No, not luck. It's a numbers game and that how the dice roll. Modern drives are complex. As such they are more likely to fail than ancient drives simply because of the complexity. They are also better engineered than old ones but the loss from complexity is greater than the game from better engineering. Plus, they are incredibly cheap compared to ancient times. Engineered products all have characteristic failure rates common across the model, the infamous bathtub curve. The factory can't do the full range of nurn-in tests they'd like to (bean counters rule), so you get a drive at the later end of the bathtub. Hence, you see elevated failure rates. The factory is willing to take a financial knock here as the loss from a few replacements is much lower than the gigantic loss from fully and properly testing every drive for hours and hours. You get a replacement. Simple odds are that it is not one of the few that will fail early, so it doesn't and you think Wow! The gods like me. Nope, statistics like me. If the factory was real smart, they would keep a small stock of fully tested drives on the replacement shelf, only to be released as under-warranty replacements. You'd be certain these drives would NOT fail and it's trivially easy to get this past the bean counters because you'd be winning back customer loyalty. And the cost of testing those few drives fully is not that much. The average bean counter has a ballistic orgasm at the thought of this, and yes they can even tell you the price they attach to winning back that loyalty. So now you know.
