'I'm running debian squeeze (fully updated from lenny) for a while without problems. However wasn't keen to tryout ext4 on this platform so far.

Not an expert on ext4 but from what I've heard and read it requires an update of grub  in order to allow grub booting the kernel from ext4.

Well - I temporarily got my serial cable to work and saw that the raid isn't mounting right.  But then I couldn't get the TX portion to work (hopefully my other thread will lead to someone willing to sell a intact working serial cable..).  Then I can go one with testing ext4

It waas a temporarily working serial cable.  I played around with it too much (because couldn't get TX to work) and broke it.  I am not much of a solderer, so that's why I asked for some assistance.

Doesn't look like an ext4 issue - more a RAID issue (can't mount raid) - I think the only way to fix that is by reflashing kernel.

yes i do. the current (2.6.32-23) kernel is working fine.  -22 has some issues.

Have you flashed a current netboot.img or just upgraded the kernel?
Have you a Gbps or a 100Mbps switch?

I booted the kernel from a spliced netboot.img and it did not work with a 100mbps sw.

These questions are for Alt-F, apologies for cannibalizing the topic :-)

just upgraded the debian package. dont forget that usual distro kernels dont work without the approciate initrd, because ethernet, sata etc modules are not compiled in (same applies here).

Yes, I booted (kexec) the kernel and initramfs.

Anyway, can you verify if the the 2.6.32-23 kernel works with a 100Mpbs switch on the dns323?

Or at least, if you have a Gbps switch and don't want to play with cables, use ethtool to advertise a 100mpbs link?

    ethtool -s eth0 advertise 0x008

ethtool eth0/ping/etc, then back to 1Gbps

    ethtool -s eth0 advertise 0x020

I would be most appreciated.

yes it works

I kexec in RAM the debian squeeze-2.6.32-5-orion5x_2.6.32-23 kernel with a striped down lib/modules, and the network works fine at 1gbps.

After unplugging the network cable from the 1gbps sw and plugging it to a 100mbps router,  the network stops working (ping doesn't work from/to the box); replugging to the gbps and it starts working again.

When unplugging the network cable from the 1gbps sw, I got
  / # [  160.383270] eth0: link down

and when plugging it to the 100mbps router, I got
  [  177.612906] eth0: link up, 1000 Mb/s, full duplex, flow control disabled

although the router led and ethtool shows a established 10mbps/full link!!!

I might have stripped the lib/modules too much.

Can do you, or anybody else running squeeze on a 100mpbs sw/router, post the loaded modules under these conditions? I don't want to generate a faulty bug report to debian.

Thanks,
Joao

what hw revision are you on? maybe that's the difference. i'm on A1.

Yes, that can be the reason, I'm on B1.

I found this bug-report (on another platform, but using the same soc)

B1 hardware. Works fine both using a 100mbps switch and with the synthetic ethtool test you suggested:

storage:/boot# uname -a
Linux storage 2.6.32-5-orion5x #1 Thu Aug 26 08:07:14 UTC 2010 armv5tel GNU/Linux

thats not the version we were talking about. check

apt-cache policy linux-image-2.6.32-5-orion5x

the minor version is important.

btw: i had the same issues as mentioned on the ml with -21 and -22 (as i already pointed out), which i think aren't related to the network speed (i always used gigabit). -23 works like a charm though.

Oops, had the new kernel but apparently hadn't reboooted.

Now I get:

Same results; everything works fine.

So, the problem seems to be on my side.

Don't know where I might have fail...  I kexec the 2.6.32-23 kernel and striped down modules and it works on 1Gbps but not 100Mbps. The same for a current netboot.img

Can you please post the loaded modules when you are on a working 100mbps link?

Other difference is that you are booting from a lenny-based netboot.img. Lenny is pre-2.6.27, I believe.
As I said in another topic: "The last kernel where 100Mbps works [for me], for the dns323, is 2.6.26.8; for 2.6.27.53 and latter it does not works anymore."
Or is the new kernel (2.6.32-23) flashed, replacing the netboot.img kernel? Can you enlight me?

Yet another possible difference is u-boot? It might initialize the hardware in different ways? I doubt, but... I'm on

Restarting system.

Hi Jcard,

good news!

Any chance that this "no CONFIG_MARVELL_PHY" Alt-f version could be reloaded (in ffp terms) on a C1 rev. to work on 100Mb?

Because if I've understood correctly the C1 and B1 have the same network hardware.

Could you share this Alt-f version please?

I have opposite problem with speed of eth0.
Instead of 1000Mbit I only get 100Mbit.

DNS323 B1 hardware
2.6.32-35 kernel
Linux nas 2.6.32-5-orion5x #1 Wed Jun 15 03:39:17 UTC 2011 armv5tel GNU/Linux

I've tried to advertise gigabit with:
set ethtool -s eth0 advertise 0x020

what happens, is that port light on switch TP-link TL-SG1008D for port where dns323 is plugged in turns off.

and ethtool eth0
Settings for eth0:
        Supported ports: [ TP AUI BNC MII FIBRE ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
