That problem in that article is S390 platform specific. They use these higher-order allocations for the S390 page tables.

Problem with /tmp d-i BUG?
After my succesfull install of sarge on a Balde 100 I doscoverd that the permissions for /tmp are wrong. It should be drwxrwxrwx but it is drwxr-xr-x also the partition recipe of d-i created a seperated tmp partition /dev/hda7 there was no ext3 filesystem created on it and /dev/shm tmpfs was mounte on the /tmp moint point anyway. /etc/fstab however has the right line for it /dev/hda7 /tmpext3defaults0 2 looks like that tmpfs behavier is triggered by the existence of the /etc/default/tmpfs file putet there by the initscripts package. And on other thing mkfs -t fstype gives only a not found. mkfs.ext3 and so on are were they should be. Any Idea to what packets I should file bug reports or why that behavier didn't show up on my i386/AMD64 boxes? greets Uwe -- Jetzt will man das Internet nicht einfach ein paar Leuten wie der IETF überlassen, die wissen, was sie tun.

Maybe for ancient pre-UltraSPARC boxes, but my dual-750Mhz SunBlade1000 alone I can hear humming in the very next room and I don't need any heat in that room because of that machine. Similarly for my Ultra60. > Don't confuse clock cycles with speed either. I'm not at all. I've been maintaining and working on the sparc Linux ports for at least 10 years.

I'm the only person who has bothered trying to write assembler optimized code for UltraSPARC in libmpeg and MESA.

Yes, hardware from back in the mid-80's, the glory days of Sun hardware when it actually was comparable to the x86 offerings of the same time frame. Some things have changed in the last 15 years :-) I have a strong vested interest in SPARC doing well, yet I can sit here and say SPARC really has lost the cpu wars. I wish other Sun/SPARC lovers could be similarly realistic. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

One thing is for sure, SPARC is definitely not the best bang for the buck. Case in point, I just dropped $2600.00USD on a new SunBlade1500 with 1.5GHZ cpus and 1GB of ram. I know that for around $700.00USD in parts you can put together your own Opteron system which is twice as powerful. The SunBlade sucks twice as much power and is twice as loud as the Opteron as well.

However, I would not recomend getting a new Sparc system to run Debian. Sparc is one of the architectures that may not make it into etch (the release after the upcoming sarge) and is generally not as well supported as x86 machines. Debian sparc developers tend not to have the latest hardware, so there may have been no testing on your configuration. For the stated application, I'd look at server class Opteron (AMD64) or Xeon systems. You need to trade off absolute specs for reliability, and don't forget to look at having a backup system as way of gaining that reliablility. -- Blars Blarson [EMAIL PROTECTED] http://www.blars.org/blars.html With Microsoft, failure is not an option.

Unfortunately not, as setting up the keyboard is one of the very last things to be done before the reboot. The best option here is to just select the same kernel version as the installer was booted with (as happens automatically during a default install).

Help with hardware choices
For the past several years I have been working for the Florida Department of State, Division of Cultural Affairs. We make grants to Florida Arts organizations and some small stipends to Individual Artists. I am currently building a new database for the Division. It is web based Apache/php4/postgreSQL software that will allow Individuals and Organizations to view and update their personal information as well as view the status of their various grants and provide staff with view/edit screens to access the complete data set. The machine I am doing the development on is a crumby slow Gateway machine, and we new from the start that this would not be our server. I have been tasked with picking the hardware, and my feeling is that SPARC offers the best bang for the buck. I have been pointed at two different lines of machines by a Systems Engineer for Sun here in Tallahassee, but I was hoping that you guys would have a better idea of what I can expect from these machines. Obviously it must run the Debian SPARC port, and while the Sun webpage lists Linux as a supported OS, they reference things like Red Hat Enterprise, which doesn't make it clear whether Debian is supported. (I mean to have a talk with them about that as well ;-) So, after that long-winded introduction, we get to my question: The machines I've been looking at are the Xeon V65X and the Ultra V210, V240, and possibly th;e v490. My question is: Which of these machines would best serve my needs as a web server/SQL server, and are there any other machines that would suite my needs better. Obviously the more horsepower the better, but I'm also on a budget of 7 to 10 thousand dollars, so the quad Xeon (at $20,000) is probably out of the question. My feeling is that the SPARC is the machine I want, but my only basis for this decission is that I own one (BTW what ever happend to Kachina Tech?). All suggestions greatfully accepted.
