Does this occur as well if you leave the ACM modem unplugged ?
Comment 2 j. alan eldridge 2001-01-16 09:49:42 EST
problem has not recurred since modem swapped out. apparently the diamon modem is
*almost* ACM compatible; note other bugs posted regarding ACM driver with this
modem (also from me). since the modem has been swapped out for a multitech
multimodem usb there have been no further incidents of any kernel-level
disturbances, ACM related or not.

Note for your hardware compatiblilty list:

MFR: Multitech
MODEL: Multimodem USB V.90/56K Fax/Modem
MFR PART #: MT5634ZBA-USB
STATUS: 100% ACM compliant; works perfectly with RH7.0
MODEM INIT STRING: AT&F0 or AT&F0M0 (to shut off speaker)
