Hi, Since i compiled the latest 2.6.3-mm4, without PREEMP, without SMP, and without ACPI, my laptop is almost working flawlessly. But, i was surprised when i unplugged the RJ45 cable, in /var/log/messages, i got : [...] Mar 2 10:48:43 pinacola kernel: r8169: eth0: Reset RTL8169s PHY [...] then, even if i plug the cable again, i got [...] Mar 2 10:48:43 pinacola kernel: r8169: eth0: Reset RTL8169s PHY Mar 2 10:49:14 pinacola last message repeated 2561 times Mar 2 10:50:14 pinacola last message repeated 5084 times Mar 2 10:50:39 pinacola last message repeated 2049 times [...] I could not even ping any host. i had to do a ifdown eth0 ifup eth0 To be able to ping the world again.
