Driver for Marwell Yukon network adapter (kernel 2.4.26-alt13) need to be updated to support new cards (e.g. Marvell "Yukon" 88E8050 PCI Express LAN Controller, Marwell 88E8001 Yukon Gigabit Ethernet controller). Old one start with "software error" and zeros in Rx/Tc of ifconfig. I rebuilt my kernel with new driver from Sisyphus (http://www.sisyphus.ru/srpm/kernel-feat-drivers-net-sk98lin) and all looks like good.
Боюсь, WONTFIX в свете выхода 4.0. Если нужно 2.4.x под M24 -- ftp://ftp.linux.kiev.ua/pub/Linux/ALT/people/yuk/kernel-2.4.33/
apparently wontfix
