Not interrupts: either IO ports or memory 

Forum: PCMCIA Installation and Configuration Issues
Re: Sad: System hangs when starting pcmcia service... (Eric Maes)

There are some very detailed instructions for diagnosing system hangs in the PCMCIA-HOWTO. The most important thing is to determine exactly when the hang is happening. Interrupts are not the problem, because even before you forced the interrupt setting, the interrupt probe completed fine (otherwise you would not have seen those system log messages). The next event that happens during the startup sequence is the IO port probe. After that, if a card is present in the adapter, the memory probe is done. So, you need to determine if the lockup depends on whether or not the Webgear card is in the slot. If it only happens with the card in the slot, it is a memory probe failure, and you need to restrict the low memory window (the 0xc0000-0xfffff window in /etc/pcmcia/config.opts). If it happens whether or not a card is present, then you need to work on the IO port windows in the config.opts file. It is possible the problem would also go away if you recompiled PCMCIA with "PnP BIOS support" switched on, since that gives better rules for automatic resource allocation. -- Dave

Feedback: Some progress... Re: Not interrupts: either IO ports or memory (David Hinds) Date: 2000, Mar 14 From: Eric Maes <eric.maes@wol.be>

David, Thanks for the tips. I have recompiled the package with Pnp bt that did not seem to make much difference. I then have experimented somewhat with ioport and memory ranges and even though I really did not know what I was doing, succeeded in getting to start the pcmcia service (I think). This is what I now see /var/log when starting up pcmcia: Mar 14 20:17:41 bilbo kernel: Linux PCMCIA Card Services 3.1.12 Mar 14 20:17:41 bilbo kernel: kernel build: 2.2.12-20 #1 Mon Sep 27 10:40:35 E DT 1999 Mar 14 20:17:41 bilbo kernel: options: [pci] [cardbus] [apm] [pnp] Mar 14 20:17:41 bilbo kernel: PCI routing table version 1.0 at 0xfd820 Mar 14 20:17:41 bilbo kernel: PnP: PNP BIOS installation structure at 0xc00fb960 Mar 14 20:17:41 bilbo kernel: PnP: PNP BIOS version 1.0, entry at f0000:b988, ds eg at f0000 Mar 14 20:17:41 bilbo kernel: Intel PCIC probe: Mar 14 20:17:41 bilbo kernel: Ricoh RF5C296/396 ISA-to-PCMCIA at port 0x3e0 of s 0x00 Mar 14 20:17:41 bilbo kernel: host opts [0]: none Mar 14 20:17:41 bilbo kernel: ISA irqs (scanned) = 9,12 polling interval = 1 000 ms Mar 14 20:17:41 bilbo cardmgr[1086]: starting, version is 3.1.12 Mar 14 20:17:41 bilbo cardmgr[1086]: watching 1 sockets Mar 14 20:17:41 bilbo kernel: cs: IO port probe 0x1000-0x1300: excluding 0x1300- 0x1307 Mar 14 20:17:41 bilbo kernel: cs: IO port probe 0x0300-0x0370: clean.

However when I try to bring up the interface either by running ifconfig by hand, or by customizing network.opts, I can just manage to enter a couple of commands after which my machine hangs... When I rebooted the machine with a non default network.opts and having set pc_debug=3 in /etc/pcmcia/ray_cs.opts, at the point where the pcmcia service was started, my console was flooded with messages: ray_dev_start_xmit busy At which point I had to reboot in single user mode to disable pcmcia at boot... So now I don't know whether I have a pcmcia or a Webgear problem... Thanks for your help - Eric
