Re: 8139too.c and 2.4.4-pre1 kernel burp

["Jörn Nettingsmeier" <nettings@folkwang-hochschule.de>]

hello jeff !

with the 8139too v. 0.9.16 from
http://sourceforge.net/projects/gkernel/ and kernel 2.4.4-pre3, i
see no more errors of the "too much work at interrupt" type.

i used to see the errors even under normal load, starting
immediately after booting.
so far, i did some nfs and flood-pinging, and all seems to be well.

if you want me to run more specific tests, let me know.

thanks,

jörn
