After you have tried the pcie_aspm boot option, also try : echo performance /sys/module/pcie_aspm/parameters/policy This will disable ASPM on PCIe and operate with maximum performance. This is what I use today on the DL380 G7. On 25.3.2013, at 09:06, Woehrle Hartmut SBB CFF FFS (Extern)

How often are you getting these crashes ? I had simular problem on my HP DL380 G7 server. I disabled Active State PowerManagement on the PCI-E express. Try it. Add pcie_aspm=off as optional boot option. Best regards, Svavar O Reykjavik - Iceland On 19.3.2013, at 15:32, Woehrle Hartmut
