Hi guys,
Let's have a look at what's going on with the DEC21150 bridge, this is on 2.4 TODO list.
Have a look at this lspci -tv output, obtained under 2.2.x:
-+-[20]---00.0 3Com Corporation: Unknown device 5257 \-[00]-+-00.0 Intel Corporation 440BX/ZX - 82443BX/ZX Host bridge +-01.0-[01]----00.0 ATI Technologies Inc 3D Rage P/M Mobility AGP 2x +-03.0 Texas Instruments PCI1225 +-03.1 Texas Instruments PCI1225 +-07.0 Intel Corporation 82371AB PIIX4 ISA +-07.1 Intel Corporation 82371AB PIIX4 IDE +-07.2 Intel Corporation 82371AB PIIX4 USB +-07.3 Intel Corporation 82371AB PIIX4 ACPI +-08.0 ESS Technology ES1978 Maestro 2E \-11.0-[02]--+-05.0 CMD Technology Inc PCI0646 +-07.0 Adaptec AIC-7880U \-08.0 3Com Corporation 3c905C-TX [Fast Etherlink]
And this obtained under 2.4.x:
-[00]-+-00.0 Intel Corporation 440BX/ZX - 82443BX/ZX Host bridge +-01.0-[01]----00.0 ATI Technologies Inc 3D Rage P/M Mobility AGP 2x +-03.0 Texas Instruments PCI1225 +-03.1 Texas Instruments PCI1225 +-07.0 Intel Corporation 82371AB PIIX4 ISA +-07.1 Intel Corporation 82371AB PIIX4 IDE +-07.2 Intel Corporation 82371AB PIIX4 USB +-07.3 Intel Corporation 82371AB PIIX4 ACPI +-08.0 ESS Technology ES1978 Maestro 2E \-11.0-[02]----00.0 3Com Corporation: Unknown device 5257
So, under 2.2.x the PCMCIA 3c905C-TX appears as if it was on the docking station, i.e. on the same PCI bus as Adaptec SCSI HBA. But on 2.2.x I don't even see the 905 but the driver (3c59x) sees it and works just fine. This is extremely strange.
Also, what about the "unknown 3COM 5257 device" - the one on the docking station - is someone working on the driver? The existing drivers don't seem to support it.
Regards, Tigran
Here is entire lspci -vvx for completeness.
