Details of lspci -> http://paste.debian.net/199820/ Any clue to this
issue?
Please let me know if anyone needs any further information.
A quality sysadmin would have checked and ironed out OS compatibility
issues before ever ordering the hardware. Keep that for future
reference. You'll need to do that legwork now:
Check Dell's website for Debian Stable and Testing support.
That's not 100% reliable.
Also check
the minimum Linux kernel version required to support the H series RAID
cards and Broadcom 5720/5800 series embedded NICs. I don't keep up
with
Dell, but this appears to be relatively new hardware: PCIe 3.0,
embedded
10GbE NICs, hot swap PCIe SSD, etc. 2.6.32 was released Dec 2009,
almost 3 years ago. I'm guessing the latest 2.6.32-5 Squeeze kernel
doesn't include the necessary drivers and/or firmware blobs for these
devices.
Right.
I run R510s with PERC H700 and as a minimum an instaalation with non-
free firmware is needed. I used this image:
http://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/6.0.0/amd64/iso-cd/firmware-6.0.0-amd64-netinst.iso
I know that R510 does not compare to R720. But even on R510 I have
problems with outdated drivers.
- the current OMSA 7 makes problems wit the old 2.6.32 kernel
- megaraid_sas (the kernel driver for the PERC) should be upgraded to
a newer version
- inserting a second PCIe Intel GB NIC with dual head causes heavy
packet loss on the first Intel NIC, this is AFAIK a PCIe kernel
problem solved in newer versions
In the future, do your homework *before* you buy, saving yourself from
these headaches.
Subscribing linux-powere...@dell.com is a must.
