Comtrol Rocketport UNIVERSAL PCI 32-port

[Vitaliy Skakun]

tried this patch

echo "~WC" > /dev/cuaR00

worked ok when I tried this a lot of times quickly, but when I try to send
larger files, it panics again :

root at pl2:~ [0]# cat 1.txt > /dev/cuaR00
root at pl2:~ [0]# cat 1.txt > /dev/cuaR00

^^^^ after this the same panic occured

the size of file is 194 bytes. same thing occured when I sent only once the
file of size=1164

after reboot:

root at pl2:~ [0]# grep panic /var/log/messages
Jan 26 17:38:49 pl2 savecore: reboot after panic: device_unbusy: called for
non-busy device rp0

also noticed the following :
when trying

root at pl2:~ [0]# cat /root/1.txt|cu -lcuaR00
Connected
~.
~.^C
^^^ cu hang

root at pl2:~ [1]# ps xau|grep cu
root    733  0.0  0.0  1284   972  p0- I     5:55PM   0:00.00 cu -lcuaR00

root at pl2:~ [0]# killall cu

And cu is killed, with no panic.

Cheers
Vit
