Subject: r8169 tx problem (1s pause with ping)
Date: Tue, 12 Jun 2007 20:41:54 -0400 [thread overview]
Message-ID: <20070613004154.GA4187@kvack.org> (raw)
Hello folks,
I'm seeing something odd with r8169 on FC7: doing a ping -s 1600 alternates
between a 1s latency and sub 1ms. Has anyone else seen anything like this?
The system in question is an Asus M2A-VM with an onboard RTL8111 (I think).
NAPI doesn't seem to make a difference. The kernel in question is currently
a vanilla 2.6.21.5. Sub-mtu sized packets behave normally.
