Bug#615860: bnx2 adapter periodically dropping received packets (pause frames)
Package: bnx2
Version: 2.6.32-5-amd64
Severity: normal
Hi all,
on my two Debian 6.0 (Squeeze) servers from HP (ProLiant DL380 G7) I have
issues with the on-board Broadcom NetXtreme II BCM5709 Gigabit
Ethernet adapters: they constantly drop received network packets, and the
Cisco routing swtich 4948 is reporting pause frames coming from the
network card during this time.
I found the exact same bug report description including an upstream fix
by David Miller here :
https://bugzilla.redhat.com/show_bug.cgi?id=640026
They increased the ring buffer size as far as I understand.
Please find further details concerning the network card and ethtool
settings bekow.
Kind regards, Joerg.
