tulip_stop_rxtx() failed (CSR5 0xf0260000 CSR6 0xb3862002) on DEC Alpha Personal Workstation 433au

[Adrian Glaubitz]

Hi guys,

I installed Debian unstable on an old digital workstation "DEC Digital
Personal Workstation 433au" (Miata) which has an on-board tulip
network controller. I'm not really using that network controller but
an off-board intel e1000 controller. However, I found that the tulip
driver produces a lot of noise in the message log, the following
message is repated periodically and spams the whole message log:

0000:00:03.0: tulip_stop_rxtx() failed (CSR5 0xf0260000 CSR6 0xb3862002)

Do you think this is related to the fact that no cable is connected to
the network controller?

The lspci output of the hardware looks like this:

test-adrian1:~# lspci

If you need anymore verbose or debug output, please let me know.

Probably something is trying periodically to open the device.
Maybe this helps reduce the message log noise:

Thanks for the patch. I will apply it to a current rc of 2.6.34 and
build a new kernel, probably not before tomorrow as I cannot reboot
the Alpha remotely as the "aboot" boot loader does not boot
automatically.

Thanks,

Adrian

Patch works perfectly. Now the message log looks pretty normal.

Thanks,

This doesn't fix the problem, it just makes the message get
emitted in a rate limited manner.

I'm not going to apply this, we need to figure out what's causing
this problem instead of merely papering over it.

Thanks.

It shouldn't be. The "stop_rxtx failed" error is because either 
CSR5_TS or CSR5_RS are still set in CSR5. This means the chip
thinks the transmit or receive protocol engines are still running.

What I suspect is the state isn't "running" by rather some other
"hung" state caused by failed (lack of) link. This has been reported
before but I've not looked that closely yet.

I might. I first have to stare at the tulip programmers guide a while
sort.
