Description of problem: I have got the problem with Acer TravelMate 4152LMi laptop and GPRS/EDGE pcmcia modem (SonyEricsson GC89). After inserting this card into pcmcia slot I can use it (but I have to pass pci=assign-busses parameter to kernel) and I can connect to my provider (using ppp scripts), but the transfer downloading files is very, very slow (about 0,5 KB/s). It is not looking like problem with the connection or with my provider; when I use this modem (and Acer TM4152LMi) under Ubuntu LiveCD 6.06 (kernel 2.6.15) it works great (download speed about 15 KB/s). My system is a fresh install (from downloaded iso image) of Fedora Core 5 (2.6.16-1.2096). I also notice there is a lot of error recieved packet (RX Error) shown with ifconfig ppp0 (about 15-20% of all recieved packets). Sorry for my English...... Version-Release number of selected component (if applicable): kernel 2.6.16-1.2096.FC5.root (distribution kernel with patch enabling dma on my laptop), but I also tried FC5 distribution kernel 2.6.15, How reproducible: Steps to Reproduce: 1.Install Fedora Core 5 2.Insert GC89 modem into pcmcia slot and connect to provider using pppd 3. Actual results: Connection is useless. Maximum download speed is about 0,5 KB/s Expected results: Additional info:

reassigning to kernel
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
Hi, I know now that it was (and perhaps it is) the problem with ACPI subsystem. This modem works fine when I boot FC5 with acpi=off parameter. But unfortunetly I can not test it with a new kernel, because I don't have this modem right now.
