Red Hat Bugzilla – Bug 101685
(ACPI) Xircom RBEM-56G-100 on Tecra 8000 no go with acpi
Last modified: 2013-07-02 22:13:41 EDT
Description of problem:
Cleanly installed Severn via nfs with linux askmethod nofb acpi=off. The system
reboots, boots linux and when it tries to start the pcmcia service it hangs with
messages that is doesn't know an IRQ for Pin A and B of the pcmcia card.
Version-Release number of selected component (if applicable):
Just reboot the laptop and wait. Always happens.
Steps to Reproduce:
1. turn on laptop
2. let it run or add runlevel 3 in grub menu
3. wait till laptop hangs after "Starting pcmcia"
That it properly activates the pcmcia slot & Xircom card and boots fine so I can
enjoy Severn :)
The problem does *not* occur when I add pci=noacpi to the grub menu line. Then
the pcmcia services are started correctly and the Xircom card is recognized and
properly activated (I can ping another host).
Can you post the output of 'acpidmp' and 'dmidecode'?
/proc/interrupts and dmesg -s40000 output from the success case could also help.
Also, if you've got a serial port on this model it would be great if we can get a look at
the boot messages from the failing boot.

Sorry for the delay guys. I've moved on to Fedora Core Test3 with kernel
2.4.22-1.2097.nptl. Just ran up2date and tried again with acpi=on. Problem
remains. Here are the final lines from the boot process
Starting pcmcia: PCI: Emabling device 00:0b.0 (0000 -> 0002)
PCI: No IRQ known for interrupt pin A on device 00.0b.0 - using IRQ 255

PCI: No IRQ known for interrupt pin B on device 00.0b.1 - using IRQ 255
Yenta IRQ list 8498, PCI irq0
