Subject: 3c59x very slow with 2.6.X
Date: Wed, 4 Aug 2004 22:03:41 +0200 [thread overview]
Message-ID: <200408042203.42367.bernd-schubert@web.de> (raw)
Hello,
somehow the network speed is reduced to 14MBit with 2.6.X on my system, with
2.4.X it has full 100MBit.
As all our systems boot diskless this is really annoying and I will reboot
2.4.27 soon.

euklid:~# mii-tool
eth0: 100 Mbit, full duplex, link ok
Any ideas whats going on?
Please tell me if you need further information.
Cheers,
Bernd
PS: Happens with 2.6.7 and 2.6.8-rc2-mm2
