I just stumbled upon an old OpenSolaris thead about the same DL585 and same symptoms: http://opensolaris-discuss.opensolaris.narkive.com/T0UTXYGZ/solaris-10-06-06-x86-hp-dl585-boot-hang-aftrer-reboot-help Their conclusion was the wfollowing and they seem to have found a fix (although I have not tested any version of Solaris on this DL585 myself): "The hang is caused when, during PCI enumeration, a PCI-PCI bridge is partially disabled when the PCI command register bits which enable IO and memory windows are cleared." Is this information useful in some way for debugging it? What else besides screenshot of the can be useful in debugging? -- Meelis Roos (mroos@linux.ee)
