Subjectkernel: eepro100: wait_for_cmd_done timeout!
Hello,

I'm seeing the message periodically:

Nov 8 09:52:59 kgate last message repeated 5 times
Nov 8 11:26:54 kgate kernel: eepro100: wait_for_cmd_done timeout!
Nov 8 11:56:12 kgate kernel: eepro100: wait_for_cmd_done timeout!
Nov 8 14:38:45 kgate kernel: eepro100: wait_for_cmd_done timeout!
Nov 8 14:38:47 kgate last message repeated 3 times
Nov 8 14:56:11 kgate kernel: eepro100: wait_for_cmd_done timeout!
Nov 8 14:57:01 kgate last message repeated 10 times
Nov 8 21:32:15 kgate kernel: eepro100: wait_for_cmd_done timeout!
Nov 8 22:57:46 kgate kernel: eepro100: wait_for_cmd_done timeout!

The source contains:

/* How to wait for the command unit to accept a command.
Typically this takes 0 ticks. */
static inline void wait_for_cmd_done(long cmd_ioaddr)
{
int wait = 1000;
do ;
while(inb(cmd_ioaddr) && --wait >= 0);
#ifndef final_version
if (wait < 0)
printk(KERN_ALERT "eepro100: wait_for_cmd_done
timeout!\n");
#endif
}

My machine is a HP Netserver LD Pro with a 200MHz Pentium Pro. I guess
a fast machine will only allow a very short time for the above loop.
Shouldn't it be fixed?

The hardware is this:
01:02.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100]
(rev 02)
Subsystem: Hewlett-Packard Company Ethernet Pro 10/100TX
Flags: bus master, medium devsel, latency 66, IRQ 9
Memory at fe8fe000 (32-bit, prefetchable)
I/O ports at ece0
Memory at fea00000 (32-bit, non-prefetchable)
