Each has 4 gigabit ethernet ports, but only 2 are working due to a PCI resource allocation failure. This seems similar to another bug (196501) that has been marked as resolved. I've tried 'hint.agp.0.disabled=1' as described in the bug report, but no difference. I also saw a recommendation about hw.pci.realloc_bars=1, but it also made no difference. I am also using several Sun X4600 compute servers. these have a similar complement of em ports and all 4 of them work with the same kernel. The X4500 supports 48 sata/sas disk drives, so it has quite a few sata controllers on the bus. I suspect that they are taking up enough space to make the allocations for the extra em devices fail, but that's just my humble guess. I've attached my dmesg output. thanks for any help or suggestions. ron. -- You are receiving this mail because: You are the assignee for the bug.
