pl2303/usb-serial driver problem in 2.4.27-pre6

Hi all,
I have a problem using GPRS inet vi my Siemens S55 attached with USB
cable since kernel version 2.4.27-pre5, the link is established well,
but then no packets get received, looking with tcpdump shows outgoing
ping packets and just few per several minutes received back. I'm unable
to ping, do nslookup, etc.
The problem started when i switched from kernel 2.4.26 (linux slackware
10.0) to 2.4.28-pre3. None of ppp otions haven't changed and all the
same options were set during kerenel config. So i decided to test all
kernels between 2.4.26 and 2.4.28-pre4 (also not working). Link works
well in 2.4.27-pre5 and stop working in 2.4.27-pre6. No "strange"
messages or errors in the logs. firewall is disabled (ACCEPT for all).
i'm using:
pppd-2.4.2
Siemens S55 mobile
USB cable (PL2303 conroller)
USB drivers:
ehci_hcd
uhci.c
pl2303.c
Thanks.
