Centos 5 was installed a year and a half ago, all works fine (5.4->5.5->5.6->5.7->5.8->5.9), 32x and 64x (a few servers).

you mention that 5.9 is ok on the same kind of hardware, can you rule out any hardware related error (disk/controller/...) by installing a 5.9 on that same server?

We have 4 identical machines, all were stable with CentOS 5 (x32 and x64). Since nothing is logged, we've had precious little information to diagnose with. A quick workaround is to manually disable the ASPM: 'pcie_aspm=performance' in grub.conf start options ('pcie_aspm=off' isn't working correctly).

# cat /sys/module/pcie_aspm/parameters/policy
default [performance] powersave
