Hi, I have been trying to get PCMCIA to work with a custom kernel. What I want is a kernel with proper ACPI support and working PCMCIA. With the stock 2.4.20 and 2.4.20-xfs I get (after modifying the PCMCIA init scripts): Linux Kernel Card Services 3.1.22 options: [pci] [cardbus] [pm] Yenta IRQ list 0408, PCI irq11 Socket status: 30000410 Yenta IRQ list 0408, PCI irq11 Socket status: 30000006 cs: memory probe 0x0c0000-0x0fffff: excluding 0xc0000-0xcbfff 0xe0000-0xfffff hermes.c: 5 Apr 2002 David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx> orinoco.c 0.11b (David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx> and others) orinoco_cs.c 0.11b (David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx> and others) orinoco_cs: RequestIRQ: Resource in use With the stock RH kernel it looks like: Linux Kernel Card Services 3.1.22 options: [pci] [cardbus] [pm] PCI: Found IRQ 11 for device 00:09.0 PCI: Sharing IRQ 11 with 00:09.1 PCI: Sharing IRQ 11 with 00:09.2 PCI: Found IRQ 11 for device 00:09.1 PCI: Sharing IRQ 11 with 00:09.0 PCI: Sharing IRQ 11 with 00:09.2 Yenta IRQ list 0608, PCI irq11 Socket status: 30000410 Yenta IRQ list 0208, PCI irq11 Socket status: 30000006 cs: IO port probe 0x0c00-0x0cff: clean. cs: IO port probe 0x0100-0x04ff: excluding 0x480-0x48f 0x4d0-0x4d7 cs: IO port probe 0x0a00-0x0aff: clean. cs: memory probe 0xa0000000-0xa0ffffff: clean. hermes.c: 5 Apr 2002 David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx> orinoco.c 0.11b (David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx> and others) orinoco_cs.c 0.11b (David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx> and others) divert: allocating divert_blk for eth1 eth1: Station identity xxxx:xxx:xxxx:xxxx eth1: Looks like a Lucent/Agere firmware version 7.28 eth1: Ad-hoc demo mode supported eth1: IEEE standard IBSS ad-hoc mode supported eth1: WEP supported, 104-bit key eth1: MAC address 00:02:2D:52:F5:E3 eth1: Station name "HERMES I" There's a real difference with the IRQ map.. So now I am stuck between a standard RH kernel without proper ACPI support (and therefore with bogus battery low messages) or with a kernel without working PCMCIA support..:-( Any solutions?
