OK, just for the record, I have upgraded 3 more machines to CentOS5.2 - a P4 Compaq D51S - new kernel runs OK - a PII Compaq Deskpro EN - new kernel runs OK - another 2*PIII Compaq ProLiant 3000 server - kernel crashes (somewhat expected, as the machine is almost identical to that I initially reported) Best regards, Wojtek ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] CentOS 5.2 kernel [2.6.18-92.1.1.el5] crashes on dual-PIII Compaq ProLiant 3000
After yum upgrade, the new CentOS5 kernel [ kernel-2.6.18-92.1.1.el5.i686 ] crashes each time early in boot process on Compaq ProLiant 3000 with dual Pentium3 CPU (600 MHz, CPU0: Intel Pentium III (Katmai) stepping 03, CPU1 the same). I get kernel panic at powernowk8_init+0x05e/0x1c3. The previous kernel [ kernel-2.6.18-53.1.21.el5.i686 ] seems to work fine. I am wondering if anyone has met this on PIII CPU ? I have found 99.9% identical problem on http://www.nabble.com/net-5501-and-RHEL5.2-td18024549.html (only esp and task slightly different from what I have seen on screen after crash, all other registers, call trace, code bytes identical to my case) , but that was on a different CPU. On the other hand, I run CentOS upgraded to 5.2 on a home PC with PIII (single CPU, Abit motherboard with i440BX chipset) with no problem. Is it normal, that powernowk8_init gets called on PIII CPU?

Ideally, I don't need too much - Firefox, I was running FedoraCore6 (very close to CentOS5) on a P4 box with 256MB of RAM, using KDE. OpenOffice (word, calc) was usable once it started, startup was rather slow. yum update was painful, I had to run it from text mode sometimes. With 384MB and IceWM or XFCE you should be OK (although I am not sure if Firefox and OpenOffice at the same time will be possible ...) One problem with old firefox is that it is (said to be) leaking memory so restarting it every few hours of so might be useful. I seem to remember that opera was advertised as being less memory hungry than firefox. > Openoffice, a little Perl/Python/C here and there.

[CentOS] total server lock-up during CentOS5.1 installation with vnc

Srv2 had Fedora Core 6 installed, recently I decided to install CentOS5.1 instead. Because the servers are located in a noisy server room, have low-end CRT monitors where installation in graphical mode is not possible, I run installation using vnc method. As the servers to not have a DVD drive, I have put CentOS 5.1 DVD image on a hard disk and booted from a CentOS boot CD ( boot.iso ) or from GRUB [ using kernel and initd from boot.iso ] and specifying HardDisk installation source. First I have installed a small rescue system on /dev/ida/c0d0p1 [ Srv2 ] with eth0 as the interface vnc was using. No problem other than grub which did not install correctly and I had to install it from rescue mode using grub-install. When installing the regular system I decided to use more fancy method: >From my_PC I started ssh session to Srv1, redirecting port 5901 to >Srv1/eth1/port 5901 (eth1 on Srv1 and Srv2 are configured to use private IP address range) Then I specified to CentOS51 installer that vnc is going to use eth1 interface. I could connect vncviewer to localhost:1 at my_PC (that is port 5901) which was forwarded over ssh to Srv1/eth1 and Srv2/eth1. This was working, I could prepare installation in custom mode, define LVM
