Hi,
It was told about a system failing to probe igb device:
...
igb 0000:04:00.1: PCI INT B -> GSI 44 (level, low) -> IRQ 44
mlx4_en: eth0: Link Down
igb 0000:04:00.1: setting latency timer to 64
igb 0000:04:00.1: PCI INT B disabled
igb: probe of 0000:04:00.1 failed with error -2
alloc irq_desc for 45 on node -1
alloc kstat_irqs on node -1
igb 0000:04:00.2: PCI INT C -> GSI 45 (level, low) -> IRQ 45
igb 0000:04:00.2: setting latency timer to 64
igb 0000:04:00.2: PCI INT C disabled
igb: probe of 0000:04:00.2 failed with error -2
...
The error -2 seems to not be the standard error, but instead
I suspect it is E1000_ERR_PHY:
#define E1000_ERR_PHY 2
and it is returned if igb_get_invariants() fails to identify
the phy->id or hw->mac.type.
lspci output:
04:00.1 Ethernet controller: Intel Corporation DH8900CC Series Gigabit
Network Connection (rev 10)

04:00.4 Ethernet controller: Intel Corporation DH8900CC Series Gigabit
Network Connection (rev 10)
igb 3.0.6-k
The lspci -v is attached in the end of file just in case.
The kernel is 2.6.32-220.13.1.el6.x86_64
Any idea what could be missing? Usually I would debug this further
but in this case I have to build an installation iso, ask to install
and get the outputs from a very limited environment... so any idea
is helpful to me :)
Thanks,
fbl
