Hi.

I've installed a puc(4) driven device on an SMP (2xPII) box and it causes
panics in a few minutes after someone dialed-in the modem connected to
(when there is some traffic going through the corresponding ppp iface).

The device is Moxa C-104H/PCI. Yes, there is no support
for this device in puc(4), but I've insert a few lines from
http://www.opennet.ru/openforum/vsluhforumID1/25871.html into
/sys/dev/puc/pucdata.c and it became ``supported'' ;) (I've also seen
almost the same lines in pucdata.c in CURRENT code)

I've tried it with RELENG_4 and RELENG_4_8 on the same SMP box with
options PUC_FASTINTR and COM_PULTIPORT turned on and off and
there is no difference - panics in all the cases.

Is there any workaround against it?

Thanks in advance.

(I'm sorry for my poor English)
