Question: Bug: Lockups on card insertion/removal... 

Forum: Installing Linux using or onto a PCMCIA device
Date: 2000, Aug 03
From: Elliot Lee sopwith

Hardware: Casio Fiva MPC-501 Software: kernel-2.2.16-17, pcmcia-cs-3.1.19 (from Red Hat pinstripe beta). Symptoms: When I remove or insert cards, the system locks up hard. I did manage to remove a 3c589 network card, but inserting it, or inserting/removing a WaveLAN/IEEE card or CD-ROM interface card, causes the described lockup. I saw a problem report in another thread that said having a syslog such as the following was a Bad Thing(tm): Aug 2 21:16:21 anode kernel: Linux PCMCIA Card Services 3.1.19 Aug 2 21:16:21 anode kernel: kernel build: 2.2.16-17 #1 Wed Jul 26 15:04:58 EDT 2000 Aug 2 21:16:21 anode kernel: options: [pci] [cardbus] [apm] Aug 2 21:16:21 anode kernel: PCI routing table version 1.0 at 0xfdfa0 Aug 2 21:16:21 anode kernel: unknown PCI interrupt router 1078:0001 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Aug 2 21:16:21 anode kernel: Intel PCIC probe: Aug 2 21:16:21 anode kernel: Ricoh RL5C475 rev 00 PCI-to-CardBus at slot 00:01, mem 0x68000000 Aug 2 21:16:21 anode kernel: host opts [0]: [isa irq] [io 3/6/1] [mem 3/6/1] [no pci irq] [lat 168/176] [bus 32/34] Aug 2 21:16:21 anode kernel: ISA irqs (default) = 3,4,7,9,10,11,12 polling interval = 1000 ms Aug 2 21:16:22 anode pcmcia: cardmgr. Please let me know what details I can provide to help narrow down the problem...

More information? Re: Question: Bug: Lockups on card insertion/removal... (Elliot Lee) Date: 2000, Aug 03 From: David Hinds <dhinds@pcmcia.sourceforge.org>

Can you post the output of "lspci" or /proc/pci, and the output of the "dump_pirq" script from the debug-tools directory of the PCMCIA source tree? -- Dave

Ok: Resolved Re: More Fiva info (Elliot Lee) Date: 2000, Aug 03 From: Elliot Lee sopwith

David sent me a solution in private e-mail which worked, so I wanted to post here in case others ever had the same problem. Add "pci_irq_list=15" to PCIC_OPTS in /etc/sysconfig/pcmcia or equivalent. I thank David for his quick and helpful responses. Now if I can just fix my code, I might be able to offer him a demo at LWCE :) Thanks again...
