Question: memory probe failure?

Hi:  I'm trying to install a MultiTech PCMCIA card modem in my Compaq Presario 1650 notebook. I am running Red Hat Linux version 5.2 (kernel 2.0.36). The card is identified as 'anonymous memory' and the system log shows that various memory ranges have been excluded. According to the PCMCIA-HOWTO, the likely cause of this problem is a memory probe failure. The suggested solution is to change the included memory ranges in the /etc/pcmcia/config.opts file. I have tried several different ranges, e.g. 0xd0000-0xdfff, 0xd8000-0xdffff, but to no avail.  The card works fine, I have been able to use it under Windows 98 (I also tried to deduce the memory range those drivers use, but that didn't help either).   Thomas ------------------------------------------------------------- probe PCI bridge probe: TI 1131 found, 2 sockets probe -m i82365 ------------------------------------------------------------- ------------------------------------------------------------- /etc/sysconfig/pcmcia PCMCIA=yes PCIC=i82365 PCIC_OPTS= CORE_OPTS= ------------------------------------------------------------- ------------------------------------------------------------- Compaq Presario 1650 linux kernel version 2.0.36 Linux PCMCIA Card Services 3.0.5 MultiTech 33.6K Modem (MT3400ZLX) ------------------------------------------------------------- ------------------------------------------------------------- /var/log/messages Nov 8 22:28:12 localhost kernel: Linux PCMCIA Card Services 3.0.5 Nov 8 22:28:12 localhost kernel: kernel build: 2.0.36 unknown Nov 8 22:28:12 localhost kernel: options: [pci] [cardbus] Nov 8 22:28:13 localhost kernel: Intel PCIC probe: Nov 8 22:28:13 localhost kernel: TI 1131 CardBus at mem 0x68000000, 2 sockets Nov 8 22:28:13 localhost kernel: host opts [0]: [ring] [pci + serial irq] [no pci irq] [lat 168/176] [bus 32/34] Nov 8 22:28:13 localhost kernel: host opts [1]: [ring] [pci + serial irq] [no pci irq] [lat 168/176] [bus 35/37] Nov 8 22:28:13 localhost kernel: ISA irqs (scanned) = 3,4,7,10 status change on irq 10 Nov 8 22:28:13 localhost cardmgr[219]: starting, version is 3.0.5 Nov 8 22:28:13 localhost cardmgr[219]: watching 2 sockets Nov 8 22:28:13 localhost kernel: cs: IO port probe 0x1000-0x17ff: excluding nothing: probe failed.

That's some old stuff... Re: Question: memory probe failure? (Thomas Schaefer) Date: 1999, Nov 11 From: David Hinds <dhinds@pcmcia.sourceforge.org>

First, you should be aware that you're using a terribly outdated release of Red Hat (and likewise, a terribly out of date version of the PCMCIA driver package). It is likely that your problem does not exist in current releases. That said, I would edit /etc/pcmcia/config.opts and delete the 0xa0000000-0xa0ffffff memory range. List only one memory range: first try the 0xc0000-0xfffff range, then try the shorter subsets of that which you tried earlier. From your system log messages, it is clear that (at least for the config.opts file you give), the problem is with the 0xa0000000 range. If fiddling with the memory ranges doesn't solve the problem, then I think the only thing to do is to get some more recent software. -- Dave

Hi: I'm still having problems trying to install a MultiTech PCMCIA card modem in my Compaq Presario 1650 notebook. I upgraded the system to Red Hat Linux version 6.0 (kernel 2.2.5, PCMCIA card services 3.1.3). The card is now correctly identified (in the mean time, I also bought a 3COM ethernet card which works just fine), but I can't get it to work. I have been trying to use minicom. Minicom attempts to dial, but there is no connection, and minicom hangs when I try to exit. I suspect it might be some sort of interrupt conflict. Windows 98 has the built in (Win)modem on COM2 (IRQ 3) and the PCMCIA modem on COM3 (IRQ 10). With the standard /etc/pcmcia/config.opts the PCMCIA card modem is assigned ttyS1 and IRQ 3. I tried to exclude IRQ3 rather than IRQ4, but that doesn't seem to help. Neither does changing the IRQ of /dev/modem to something like 0 or 10 using the setserial command. (IRQ10 has an interesting effect: Minicom claims that I am already on line). ------------------------------------------------------------- probe PCI bridge probe: TI 1131 found, 2 sockets probe -m i82365 ------------------------------------------------------------- ------------------------------------------------------------- /etc/sysconfig/pcmcia PCMCIA=yes PCIC=i82365 PCIC_OPTS= CORE_OPTS= ------------------------------------------------------------- ------------------------------------------------------------- Compaq Presario 1650 linux kernel version 2.2.5-15 Linux PCMCIA Card Services 3.1.3 MultiTech 33.6K Modem (MT3400ZLX) ------------------------------------------------------------- ------------------------------------------------------------- /var/log/messages Nov 16 10:33:00 localhost pcmcia: Starting PCMCIA services: Nov 16 10:33:00 localhost pcmcia: modules Nov 16 10:33:00 localhost kernel: Linux PCMCIA Card Services 3.1.3 Nov 16 10:33:00 localhost kernel: kernel build: 2.2.5-15 #1 Mon Apr 19 23:00:46 EDT 1999 Nov 16 10:33:00 localhost kernel: options: [pci] [cardbus] [apm] Nov 16 10:33:00 localhost kernel: Intel PCIC probe: Nov 16 10:33:00 localhost kernel: TI 1131 PCI-to-CardBus at bus 0 slot 10, mem 0x68000000, 2 sockets Nov 16 10:33:00 localhost kernel: host opts [0]: [ring] [pci + serial irq] [no pci irq] [lat 168/176] [bus 32/34] Nov 16 10:33:00 localhost kernel: host opts [1]: [ring] [pci + serial irq] [no pci irq] [lat 168/176] [bus 35/37] Nov 16 10:33:00 localhost kernel: ISA irqs (scanned) = 3,4,7,10 status change on irq 10 Nov 16 10:33:00 localhost pcmcia: cardmgr.
