Re: [Acx100-users] latest acx100 not working

[Toni I. <ton...@ya...>]

Okay I have compiled version
http://195.66.192.167/linux/acx_patches/acx-20051010_txstop_fix.tar.bz2
and it works fine. But why? What is different in this
version? What is _txstop_fix? Maybe my kernel is bad
and I should recompile it!
