| |
Summary -------
Activating the option 'Local APIC support on uniprocessors' prevents the network device '8139too' from transmitting any packet.
Full description ----------------
In a kernel 2.4.20 compiled with the option 'Local APIC support on uniprocessors' I can successfully load the module '8139too' but the network device doesn't work at all, I can't even do a single ping.
I also see numerous times messages like :
NETDEV WATCHDOG: eth0: transmit timed out eth0: Setting 100mbps full-duplex based on auto-negotiated partner ability 45e1.
The workaround is to boot the kernel with the option 'noapic' or recompile it without the option 'Local APIC', and then the network device works perfectly.
Kernel version --------------
Linux version 2.4.20 (nico@kurumi) (gcc version 2.95.4 20011002 (Debian prerelease)) #1 Mon Feb 10 03:27:37 CET 2003 From the debian package 'kernel-source-2.4.20_2.4.20-5_all.deb'.
