vmlinuz-2.6.29-1-11May on IIfx

vmlinuz-2.6.29-1-11May on IIfx

[Riccardo]

Hi,

since I was so happy of the reults on the Q950, I tried my luck with 
the current kernel on the IIfx .

The kernel completes boot. The keyboard works; I'm able to login.
But any activity on the ethernet (remlote login or just a Ping) gives 
me:

trigger_send() called  with the transmitter busy

and after a bit


eth0: mismatched read page pointers 45 vs  c.

booting into 2.6.26 I see the driver used is the mac8390. From dmesg of 
2.6.26

[42949395.010000] mac8390.c: v0.4 2001-05-15 David Huggins-Daines 
<dhd@debian.org> and others
[42949395.030000] eth0: Memory length resource for slot A not found, 
probing
[42949395.040000] eth0: EtherNet card in slot A (type apple)
[42949395.050000] MAC 00:80:ad:13:7c:d0 IRQ 57, 32 KB shared memory at 
0xfaad0000,  32-bit access.


I hope that helps a bit,

Did this ethernet card work in an older kernel? The card type detection
in mac8390.c is partially based on guesses and just trying different
cards, as I remember. It's possible that it's detecting the wrong type,
particularly since it isn't finding all the NuBus ROM resources it is
expecting to be present on this card type. I suspect that it's not
accessing the card correctly. Both the error messages are that the
card isn't in a sane state based on what the driver tried to do.

Incidentally, "apple" is the default type for any card the driver
thinks it can use but can't identify with 100% certainty.

The 'mismatched read page  pointers' I've seen on the EtherNEC 8390 based card 
as well, it seems to indicate that the receive buffer overruns. I'm using a 
timer interrupt there, so that is expected to happen. 

Might 'trigger send called with tx busy' also indicate a failure to receive the 
txdone interrupt? Maybe you're not getting any interrupts from the card? What 
does /proc/interrupts register regarding the 8390 driver?

maybe I did not express myself clearly: in 2.6.29 the card doesn't work 
and I typed the error message manually,

I then rebooted into 2.6.26, where the card still worked, and pasted 
its dmesg.

under linux, 2.6.29 I get:

mac 57: 74 8390 Ethernet

I attempt to ping a host, which fails, then it says:

mac 57: 86 8390 Ethernet

This commit looks a bit suspect -- it was not CC'd to this list -- in 
particular the Makefile change:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ca17584bf2ad1b1e37a5c0e4386728cc5fc9dabc

So now mac8390.c and 8390.c both #include "lib8390.c"... might this 
perhaps lead to the wrong ei_inb/outb etc in the final link?

It does seem like an odd change. It would be nice if this list got
copied on changes to any nubus drivers, but I suppose it's not anywhere
on the maintainers list. It might be something to bring up with David
for any future changes to nubus network cards.

I'll try to find some time to build a kernel and try it out. I have
several cards that use this driver.

My apologies. I did misunderstand your original message.

Probably the change looked sufficient trivial/innocent. Trivial updates for core
changes are usually posted on the subsystem mailing list only.

Good, thanks!
