Hello Ugo,
1) can you please check that the processor supports the PAE?
# cat /proc/cpuinfo
...
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow pni
...
e.g. 'pae' flag should present.

flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 mmx fxsr sse pni syscall mp mmxext 3dnowext 3dnow
So it looks OK.

2) it may be initrd related issue. are you sure that initrd image for new kernel has been created correctly?
Could you please check the /etc/grub.conf (or lilo.conf if you are using lilo). There should be an entry for the newly installed ovzkernel-PAE-2.6.18-8.1.8.el5.028stab039.1
Do those files mentioned in 'kernel' and 'initrd' sections exist in /boot? Could you please try to recreate initrd file using the following command? Are there any errors reported?
# mkinitrd -v -f /boot/initrd-2.6.18-8.1.8.el5.028stab039.1PAE.img 2.6.18-8.1.8.el5.028stab039.1PAE

All files are there. I tried recreating the file like you suggested, no error.

It is quite troubling, that, according to the sysadmin at the colocation facility, even the -smp kernel, which was running fine before the upgrade, doesn't boot anymore...

3) If all of this won't work, please, try to attach a serial console to the node or at least KVM. This will allow us to collect the boot logs or at least to see the last messages. If you are going to the colocation facility, please, take a photo with you and take a photo of a screen of a hanged node. If we are lucky the last messages can contain useful information.

Hmmm, I don't have my digital camera with me, only my cell. Not sure if I have a null modem cable. I'll see. I will have, for sure, a paper notepad, and a pen  .
Thanks!
