next in thread | raw e-mail | index | archive | help
I have installed 4.3-RELEASE onto my old 486DX2 and are using it
as a firewall/router towards my DSL modem. Several times it has gotten into a
state with this "microuptime went backwards" message all over the console
and only a reboot could stop it.
I have tried to search the archives but found nothing that could explain/solve
this problem
Ideas anyone? I include the dmesg and kernel config below.
Thanks for any help.
