Hi, I just tried compiling 2.4.14. At our installation we compile the following network drivers in by default: 3c509, 3c59x, SMC Ultra, Decchip tulip, Etherexpress Pro/100, SMC Etherpower II Now the machine that i was booting the kernel on (called testbed12) has a _single_ 3c59x interface and an ATM interface (ENI55). The 2.2.18 kernels had no problem with this. But it seems the 2.4.14 kernels do! 2.4.14 detected it as an SMC Ultra and gave me a *bonus* interface eth1 as 3c59x. And hence network connectivity does not work. I am reproducing the log files below. I have made no changes to the configuration files too. ---------- 2.4.14 kernel ------------------------------------------- Nov 28 12:23:51 testbed12 kernel: Floppy drive(s): fd0 is 1.44M Nov 28 12:23:51 testbed12 kernel: FDC 0 is a National Semiconductor PC87306 Nov 28 12:23:51 testbed12 kernel: smc-ultra.c:v2.02 2/3/98 Donald Becker (becker@cesdis.gsfc.nasa.gov) Nov 28 12:23:51 testbed12 kernel: eth0: SMC EtherEZ at 0x280, 00 00 C0 57 21 F4,EEPROM IRQ 10 programmed-I/O mode.
