First many thanks for this effort!

... especially as your patches seem to improve my qube2's stability
and performance! :-))

I was still observing some system hangups under heavy (network) load,
which I cannot reproduce _with_ these patches.

Network traffic seems to be zippier: Simple 'rsh ...' connections
seems to react more promptly. With ttcp and 32k buf len ('-l 32768') I
can reach tcp transfer rates up to 2.4 MBytes/sec (before only up to 1

Dmesg output of my customized kernel with your patches is appended
(couldn't use your compiled one due to missing features (pppoe0, ral0
et al.)). If you need more verbose kernel output tell/mail me the
needed kernel compile options you need for getting it.

Thanks again, Markus.
