Hi All, I just wanted to let you know that adding the noapic to the grub.conf file seems to have cured the lockup error issue I was experiencing on my IBM box. Also in the BIOS the APM mode was on. Turning it off did not fix the problem but adding the noapic did the trick! By the way my Centos is 2.6.18-92.1.10.el5 So its been running nonstop now for over a day and a half with no problems. Thanks, for the help. Jon VA3RQ
Jon,
This sounds to me like a problem in the PC itself.
This is a shot in the dark: the APIC's on on some PC's are flaky under linux.
You could try adding noapic to the kernel boot line in /etc/grub.conf:
# grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,0) # kernel /boot/vmlinuz-version ro root=/dev/hda1 # initrd /boot/initrd-version.img #boot=/dev/hda default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-92.1.13.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-92.1.13.el5 ro noapic root=LABEL=/ initrd /boot/initrd-2.6.18-92.1.13.el5.img title CentOS (2.6.18-53.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-53.el5 ro root=LABEL=/ initrd /boot/initrd-2.6.18-53.el5.img
I have an IBM box which does has to have this done in order to stay working. The groub.conf above is from that box.
