Hi, Grzeniek, Please open a bug in http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI And attach the dmesg and "cat /proc/interrupt" both with and without "acpi=off" boot parameter. acpidump may be needed as well. Thanks, Rui -----Original Message----- From: linux-acpi-owner@xxxxxxxxxxxxxxx [mailto:linux-acpi-owner@xxxxxxxxxxxxxxx] On Behalf Of Grzeniek Sent: Thursday, October 11, 2007 4:40 AM To: linux-acpi@xxxxxxxxxxxxxxx Subject: Problem with GPRS modem Hi, I've got a SonyEricsson GC89 GPRS/EDGE pcmcia card (serial), but I can't get to work it (on my laptop Acer TravelMate 4152LMi). The problem is that the connection is very, very slow (download rate about 0,5KB/s) and I've got more then 20% rx errors on ppp0 interface. The system (I tried FC5, FC7, Ubuntu 6.04, Ubuntu 7.04 and Ubuntu 7.10) can recognize this card, I can make ppp connection to GPRS/EDGE network. But this connection is really very slow, and I think. What I found is when I boot system with acpi=off parameter everything works great, I' ve got transfers about 20-25KB/s with no rx errors on ppp0 interface. I'm really not sure if this problem is related to acpi subsystem (maybe this is pcmcia or pppd problem), but I have to try. >From dmesg: pccard: CardBus card inserted into slot 0 PCI: Enabling device 0000:03:00.1 (0000 -> 0001) ACPI: PCI Interrupt 0000:03:00.1[A] -> GSI 16 (level, low) -> IRQ 16 0000:03:00.1: ttyS4 at I/O 0xa000 (irq = 16) is a 16550A lspci -vv: 03:00.1 Serial controller: Broadcom Corporation EDGE/GPRS data and 802.11b/g combo cardbus [GC89] (rev 03) (prog-if 02 [16550]) Subsystem: Unknown device 18de:0003 Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort+ <TAbort- <MAbort- >SERR- <PERR- Interrupt: pin A routed to IRQ 11 Region 0: I/O ports at a000 [size=256] uname -a Linux localhost 2.6.22-12-generic #1 SMP Sun Sep 23 18:11:30 GMT 2007 i686 GNU/Linux I really don't know how to make this card working properly, and I need your help.
