In kernel version 2.4.x (x from 0 to 2-ac3), the
smc-mca driver gives many errors like the following on
the console log:
io mapaddr 0xXXXXX not valid at smc-mca.c:YYY!
where XXXXX is an address within the shared-memory
assigned to the adapter card, and YYY is 378, 398 or
408.
I have tested the driver on two IBM MCA systems - a
9577 and an 8590. I have tried three different network
adapters in each machine:
WD Ethercard PLUS 10T/A (WD8003W/A)
SMC Ethercard PLUS Elite/A BNC/AUI (WD8013EP/A)
SMC Ethercard PLUS Elite/A UTP/AUI (WD8013WP/A)
All the adapters give the errors, in both machines.
All adapters and both PS/2s are known to be good with
kernel 2.2.17.

AFAIK, it is a bug in the driver. That output is generated by
arch/i386/lib/iodebug.c, a routine to catch buggy drivers like that.
Look at
include/asm-i386/io.h, line 112 or so:
/*
* Temporary debugging check to catch old code using
* unmapped ISA addresses. Will be removed in 2.4.
*/
#if CONFIG_DEBUG_IOVIRT
extern void *__io_virt_debug(unsigned long x, const char *file, int line);
extern unsigned long __io_phys_debug(unsigned long x, const char *file, int li
ne);
#define __io_virt(x) __io_virt_debug((unsigned long)(x), __FILE__, __LINE__)
//#define __io_phys(x) __io_phys_debug((unsigned long)(x), __FILE__, __LINE__)
#else
#define __io_virt(x) ((void *)(x))
//#define __io_phys(x) __pa(x)
#endif
So you should mail driver mantainer, if it is known....

Yes. Its someone using readb and friends on an unremapped address. In this
case I had a look and a guess at a fix is in ac5 (out RSN)

You'll be glad to hear that the driver is now working perfectly. Thanks!
