Yes, F6FBB and F1OAT has made a patch to z8530drv, thats is a "tx interrupt
watchdog".
found at: ftp://ftp.f6fbb.org/pub/distrib/fpac-linux/rose-patch/scc.tgz

Yes, i have no ethernet card, sound card.. etc neighter support for it, i
have cleaned out everything thats not needed, i�ll use io 0x300 and int 10
for the Baycom USCC card now, and i know 100% there is nothing on this irq
and io. :/

Dosn�t help here.. :/

Hm.. i�ll have used a homemade scc card before, and there was not this
problem, the differnce is there is only one z8530 (2ports),
and i used "divider", at the baycom card i use "dpll" and there is 2 z8530
(4ports) at same irq.
Hm.. btw, i have one 9k6 port on the baycom card, this port use "divider",
and on this port have the RTS/PTT never stopped to work... perhaps
something?

Hm, okay.. i will test the orginal driver in your z8530drv package today,
i�ll just get a report that another port was down,
not the port that usualy gets down.. :/
