system lock up with ichsmb driver

We have been able to consistently lock up a Pentium-M
system (Intel 6300ESB IOCH) by sending a
SIGINT/SIGTERM signal to an application while it is
accessing the smbus.  If we ignore signals in the
application or if we remove the PCATCH option on the
tsleep() call within ichsmb_wait() in ichsmb.c, the
SIGINT/SIGTERM signal does NOT cause the system to
lock up.

Has anyone else seen this behavior?  Does anyone know
of a fix?

We are running from a 4.3 base.

Thank you,
