On the RELENG_7, ASPM was enabled in the BIOS (INTEL DH55TC MB), so I have disabled that for now to see what happens. On the RELENG_8 machine, its been a LOT better since 7.1.8, but again it happened last night during a backup
My machine is still holding up but it doesn't yet handle full traffic.
I've just noticed something strange: both em0 and em1 are marked
"active" in ifconfig even though there's no cable in em1 port :(
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>
ether 00:25:90:0b:77:5c
inet 10.10.0.33 netmask 0xffffff00 broadcast 10.10.0.255
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
em1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>
ether 00:25:90:0b:77:5d
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
(100 mbit is expected)
Note "AER 1 0 fatal 0 non-fatal 1 corrected" in my output - I don't know
if it's significant.
