2.6.0-test4(-mmX) via-rhine ethernet onboard C3 mini-itx doesn't work

[Danny ter Haar]

Subject says all! :-)

2.6.0-test3-mm2 still works (as does 2.4.21-rc2).

vanilla 2.6.0-test4 & test4-mm[45] & the onboard ethernet doesn't seem to work.
No kernel panics, it just doesn't work :-(


Both have same ethernet driver:

Try a kernel without ACPI and/or APIC support.

Yup, adding acpi=off "fixed" the problem.

It's standard APIC bug that no one care!

I have via_kt-400 on ecs_l7vta, just check my previous post:

Same to me.

I report this bug probably 4 times! And it was since early 2.4.20, then APIC
changes, so I can use if.

Slackware GNU/Linux (current).

P.S. I you wont to use eth with that kernel, silmpe uncompile
CONFIG_X86_UP_APIC and use APM.

PP.S. Maby you have ATI card? Bug with setfonts and loadkeys on 1 tty it's

ok, will do that for now.

nope, mini-itx has everything on board. I intend to use mine as a firewall

Yep, right, perhaps they has not.

I use 2.4.22-rc2 (APIC works fine with via-rhine), so I patch -ac3 on that
kernel too.

if you enable APIC (and not ACPI) then you start using a different BIOS
table for IRQ routing. Several BIOSes have bugs in this table since it's
not a table that is generally used by Windows on UP boxes. Saying that
it's the kernel's fault is rather unfair; most (if not all) distros for
example ship with APIC disabled for this reason. It's nice if it works
for you but there's quite a few boxes out there that just can't work....
Don't configure it if you have such a box.

Do not be anger Arjan, but it[1] works from time to time, so it is permanently
kernel/APIC bug.

Take care.

What I've been seeing lately is people complaining it used to work with
previous kernels but later ones don't. One possible explanation would be
that VIA chip sets (explicitly or through one of their specific properties)
used to be blacklisted before (and thus APIC silently disabled).

The reports I get indicate that _something_ in the kernel changed. I
suspect it's the ACPI code (best viewed with Intel chipsets), but that's
speculation.

It's impossible to have an APIC bug on a C3 board, because the processor
simply doesn't have one!

Another respondent today said that disabling ACPI (note ACPI != APIC)
solved his problems.

I saw your previous report. It was basically information-free and impossible
to base any problem analysis on. If you want your bug reports to have a
chance of being acted upon, follow the documented bug reporting procedure.

Some days ago a patch for 2.6 has been posted on bugzilla, (see some of the 
last entries of Bug #10).
This one got IO-APIC + ACPI working for the first time in a year on my EPOX 
8k5a3+.
(via-rhine, usb , sound )

Please try !

P.S. there's also a patch for 2.4 (search for "Fixing USB interrupts problems" 
in the subject)

Most users are more than happy to provide additional information when asked
for it. In my personal experience, the documented bug reporting procdure is
a time consuming way of producing lots of information, most of which is
irrelevant to the case in question, and which is usually lacking the
information _I_ am looking for. For me, it tends to be less work to ask the
user for the specific details than to sift through a lengthy standard bug
report looking for it. YMMV, of course.

I tried 2.6.0-test4-mm2 on other C3 (bought several units including for in my car ;) and that one simply froze after detecting the partiton table of the ide harddisk. adding acpi=off even made then one move again.

When confuses me if that it works with prior kernels and suddenly fails
with later/greater kernels.

Ah well, it's now better known and probably some clever individual will
eventually figure it out and post a patch ! ;-)

Exactly. I installed from CD with 2.4.18-something and that seemed to work.
It's sort of natural that your upgrade to a newer kernel and since 2.6.0 
is to be declared "stable" i thought it would be best if it's known that
there are still problems.

Yep, 2 different C3's, one with IDE freezes and one with network probs
suddenly work fine.

The chipset does and not writing PCI_INTERRUPT_LINE and other things
properly can cause problems if its directing interrupts to the chipset
I/O APIC wrongly not the PIC and thus the CPU

You mean PCI initialisation (and thus ACPI) can break the I/O-APIC
even though the kernel never actually accesses the I/O-APIC per se?
Ok, I see how that could happen.

In paticular onboard VIA stuff uses the upper bits of the
PCI_INTERRUPT_LINE register to do IRQ routing as well as the PIN stuff
that PCI expects

This is also apparent in the 2.4.22 stable kernel .. I wasn't able to get my

This patch doesn't apply to -mm4/5.

Indeed. And your detailed bug reports (as outlined earlier today by Len
Brown) are going to help with that.
