Did you try booting with "pci=assign-busses" added to the kernel command line as dmesg says? If that doesn't fix the issue can you see if you can reproduce it using vanilla-sources-2.6.17?
(In reply to comment #1) > Did you try booting with "pci=assign-busses" added to the kernel command line > as dmesg says? Yes, the boot error message about the transparent proxy disappears but the multiport bluetooth device and the modem are still not detected. > If that doesn't fix the issue can you see if you can reproduce > it using vanilla-sources-2.6.17? I'll try that as soon as I get a minute and report back. -- Regards, Mick
It would be more worthwhile testing the latest development kernel, currently 2.6.18-rc4 If the problem exists there, please attach "lspci -v" output from that kernel with pci=assign-busses
Thanks Daniel, I have just booted the vanilla 2.6.18-rc4 and have saved all relevant files under the same links I've listed above. In addition, here's the log after a bootup: http://michaelkintzios.fastmail.fm/evo_n600c/log_messages.txt I still cannot see the multiport-bluetooth device, or the modem. Not sure if I need to run setserial or do any magic for these to appear (like I have to do for the IrDA). -- Regards, Mick
I found this link which may help your understanding with regards to the Compaq multiport, although mine does not have a wlan chip attached to it, but bluetooth. http://joshua.raleigh.nc.us/cpq_wireless.html HTH. -- Regards, Mick
Final thought: There is of course a possibility that there is nothing wrong with the kernel, but that the hardware is for some reason damaged, but isn't it too much of a coincidence that neither the bluetooth chip, nor the modem are detected? What could have damaged both at the same time? The laptop has no signs of a drop or knock on its casing . . . -- Regards, Mick
Latest findings: Using the vanilla kernel does not get me any nearer to detecting the illusive hardware. However, I just booted a Knoppix CD with the 2.6.17 kernel and the modem is now detected! ================================================= # lspci 0000:02:04.0 Communication controller: Agere Systems LT WinModem (rev 02) Subsystem: AMBIT Microsystem Corp.: Unknown device 0450 Flags: bus master, medium devsel, latency 66, IRQ 11 Memory at 40180000 (32-bit, non-prefetchable) [size=256] I/O ports at 2840 [size=8] I/O ports at 2000 [size=256] Capabilities: [f8] Power Management version 2 # lspci -v 0000:02:04.0 Communication controller: Agere Systems LT WinModem (rev 02) Subsystem: AMBIT Microsystem Corp.: Unknown device 0450 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 66 (63000ns min, 3500ns max) Interrupt: pin A routed to IRQ 11 Region 0: Memory at 40180000 (32-bit, non-prefetchable) [size=256] Region 1: I/O ports at 2840 [size=8] Region 2: I/O ports at 2000 [size=256] Capabilities: [f8] Power Management version 2 Flags: PMEClk- DSI+ D1- D2+ AuxCurrent=160mA PME(D0-,D1-,D2+,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME- ================================================= Still no idea why my Gentoo OS will not see it, or what I need to do to make it visible to the kernel. I had no success with Knoppix and the multiport/bluetooth chip. -- Regards, Mick
Could it be that you have forgotten to enable PCI express support or something like that? Please attach your .config
(In reply to comment #8) > Could it be that you have forgotten to enable PCI express support or something > like that? Please attach your .config Blast! Yes, I had left pci express out (thinking that this is a relatively old 1997-8 vintage laptop). Now that I've included it I can see the ltmodem, load the module and dial out - wey, hey! I must apologise at least for raising half of this bug report because the transparent bridge error is gone. However, I am still getting nowhere with the bluetooth chip. Any pointers please? -- Regards, Mick
Well, can you explain what you have tried? I think there is a Gentoo bluetooth guide as well - have you read that? I have never used bluetooth so don't really know where to start giving advice.
If you're still stuck on bluetooth and have exhausted the usual support mediums then it would probably be best if you open a new bug for that.
(In reply to comment #11) > If you're still stuck on bluetooth and have exhausted the usual support mediums > then it would probably be best if you open a new bug for that. Thanks Daniel. I suspect that the bluetooth may be a hardware problem. I'll have another go at the mailing list - just in case. -- Regards, Mick
