(see below) looks like a driver bug !? does anybody have a clue what`s going wrong here? regards roland #lspci 00:00.0 Host bridge: Cyrix Corporation PCI Master 00:0f.0 Ethernet controller: National Semiconductor Corporation DP83815 (MacPhyter) Ethernet Controller 00:12.0 ISA bridge: Cyrix Corporation 5530 Legacy [Kahlua] (rev 30) 00:12.1 Bridge: Cyrix Corporation 5530 SMI [Kahlua] 00:12.2 IDE interface: Cyrix Corporation 5530 IDE [Kahlua] 00:12.3 Multimedia audio controller: Cyrix Corporation 5530 Audio [Kahlua] 00:12.4 VGA compatible controller: Cyrix Corporation 5530 Video [Kahlua] 00:13.0 USB Controller: Compaq Computer Corporation ZFMicro Chipset USB (rev 06) #dmesg |egrep "natsemi|eth" natsemi dp8381x driver, version 2.1, Sept 11, 2006 natsemi 0000:00:0f.0: setting latency timer to 64 natsemi eth0: NatSemi DP8381[56] at 0x4010000 (0000:00:0f.0), 00:00:00:00:00:00, IRQ 10, port TP. eth0: DSPCFG accepted after 0 usec. eth0: link up. eth0: Setting full-duplex based on negotiated link capability. #natsemi-diag -aa natsemi-diag.c:v2.08 2/28/2005 Donald Becker (becker@scyld.com) http://www.scyld.com/diag/index.html Index #1: Found a NatSemi DP83815 adapter at 0xf800.
