Sad: Tecra 700CT + Linksys = "Tx timed out" 

Forum: PCMCIA on Toshiba laptops
Date: 2000, Jan 26
From: Judah Milgram Jud 

Hi,

This is either a bug report or a user problem, not sure which.

System: Toshiba Tecra 700CT
        Slackware 3.x
        Kernel 2.0.38
        pcmcia 3.0.14 (should I be using 3.1.x?)
        Brand new Linksys Etherfast PCMPC100 10/100 PC card
        removed other PC card (a modem, which works)

In /etc/rc.d/rc.pcmcia:
        uncommented PCIC=i82365
        PCIC_OPTS="do_scan=0 irq_list=9" (added this
        as part of troubleshooting; tried different
        variations along the way)

In /etc/pcmcia/pcmcia.opts:
        exclude irq 4
        ... and 3,5,7,10 along the way.

When I do /etc/rc.d/rc.pcmcia start I get the two beeps
        and dmesg tells me: 

Linux PCMCIA Card Services 3.0.14

Also, /var/run/stab says:

Socket 0: Linksys EtherFast 10/100 Fast Ethernet
0       network pcnet_cs        0       eth0
Socket 1: empty


All this says to me that the Linksys card is recognized,
the driver loads, the irq is set to 9 (which I determined
to be free), and the ioport set to 0x300 (also free). However,
I can't ping out. And I get these
in the system logs:

eth0: Tx timed out, lost interrupt? TSR=0x43, ISR=0x3, t=1000.
eth0: Tx timed out, lost interrupt? TSR=0x43, ISR=0x3, t=6500.
eth0: Tx timed out, lost interrupt? TSR=0x43, ISR=0x3, t=12000.
eth0: Tx timed out, lost interrupt? TSR=0x43, ISR=0x3, t=12000.

NB network configuration should be OK, is essentially
unchanged from back when it worked via another network
device. Also, ifconfig reports eth0 up with sensible
parameters. route -n too.

I'm thoroughly perplexed, my research turned up only the
do_scan=0 idea, and sadly this didn't help. Any advice
greatly appreciated.

Just some followup: 

1) per suggestion seen in similar problem on c.o.l.portable,
   I tried excluding higher ports (0xa00 up) in config.opts.   
   No success, but not surprising since it always chose 0x300  
   anyway.

2) tried to get it up and running on Windows 95. No success,
   but this is likely due to my lack of W-95 expertise.
   It does seem to start up the card (lights on pigtail,
   beeps) but it can't see the network. Anyway it wanted
   files from Windows disk 19 and my set only goes to 13,
   so who knows what's going on there.

3) could the Tx timed out problem stem from problems elsewhere
   in the network? I ask because the whole network is new
   at once, and I haven't confirmed that the desktop (only
   other machine on network) really is able to communicate
   with network. I can ping to the laptop, it loses all 
   packets but I do see the LED on pigtail blink at the ping
   rate.

thanks again,

Judah

... and more yet

For what it's worth: tried installing pcmcia 3.1.8, still
no go. This time I get messages along the lines of

memory_cs: mem0: anonymous: unknown size
memory_cs: mem1: anonymous: unknown size

BTW I noticed a possible point of confusion in the
install procedure. If installing over an existing
setup, it "seems" like the old config files in
/etc/pcmcia get moved to *.O, like the HOWTO says.
But /etc/rc.d/rc.pcmcia seems to remain unchanged, the
new script being installed as *.N. I didn't notice this
before and was trying to start up services with
an old rc.pcmcia. I since fixed that and none of my
previous problems went away. But it is a potential
source of confusion (unless it's in the HOWTO and I
missed it).

OK, enough time wasted on this thing. PLIP doesn't work
on this machine either, making it almost completely
un-networkable. Grrrr, will research my next laptop
purchase more carefully.

grateful for all advice,

Judah

Ok: Yay!

Thanks to David Hinds for providing the critical suggestion.

This works: 

 Tecra 700CT
 Linux 2.2.6
 pcmcia 3.0.5 (or 6?)
 PCIC_OPTS="do_pci_scan=0"

Also worked: same as above with Linux 2.0.38 and pcmcia 3.0.9

also: just adding that PCIC option and doing restarting (with rc.pcmcia restart - maybe I also tried "stop"+"start") didn't work, I had to do a cold reboot. I addition, during much of this saga the machine was in resume mode without my noticing it; possibly this was a factor too.

Thanks again Dave!
