[hsflinux] compressor dropped pkt

[Ross Melin]

Hello all,

I am using the hsfmodem-7.18.00full_k2.6.8.1_12mdk-1mdk.rpm with Mandrake 10.1 
on my Dell Inspiron 2650. I getting kernel error messages about dropped 
packets. 
I am able to connect OK. I have tested with two other modems, a Motorola 
serial modem, and an Intel chipset EP536 softmodem. I can connect to either 
at a variety of speeds, but then get almost no data throughput.
Here is a typical sample from /var/log/syslog:
