Timeouts on EP-HDA3+ Motherboard

Hello!

I'm getting reproducable errors when Samba is transferring large files:

eth0: Transmit timed out, status 0000, PHY status 786d, resetting...

This is not the case if such a file is transferred using FTP.

And yes, im running with "pci=noacpi,usepirqmask,biosirq noapic" (otherwise the problem happens so frequently that eth0 is more or less unusable).

I know that the Via-Rhine hardware and/or the driver isn't perfect, but b/c i'm having a reproducable testcase here, i thought i might be able to assist in fixing this problem (if it is fixable at all, of course). In addition, as this machine is mainly a Samba fileserver it's getting pretty annoying.

I'm using an Epox EP-8HDA3+ Athlon64 Motherboard with VIA K8T800 chipset. The board has two on-board ethernet devices, the VIA Rhine 100BaseT and an 3Com/Marvell 1000BaseT chip. Both are sharing it's interrupts with each other and on-board USB devices (however i'm neither using the Marvell nor any USB peripherals):

PCI: Sharing IRQ 12 with 0000:00:10.1

Thanks and best regards,

What kernel? (my crystal ball is in repair)

Roger

Oops. I'm sorry, i thought the version number of the driver might be enough...

The box is currently running 2.6.7 vanilla. I've installed it starting with 2.6.1 (as 2.4.x doesn't support the hardware proberly) and the problem has existed ever since.

Best regards,

Peter

Argh! I didn't copy that part into my first mail:

via-rhine.c:v1.10-LK1.1.20-2.6 May-23-2004 Written by Donald Becker
eth0: VIA VT6102 Rhine-II at 0xe8187000, 00:04:61:fe:fe:fe, IRQ 12.
eth0: MII PHY found at address 1, status 0x786d advertising 05e1 Link 40a1.

Sorry, again.

Best regards,

Try 2.6.8-rc3 or later. Let me know if it works (if it doesn't, I'm not sure I want to know :-/).

Roger

As this is a production machine i haven't had the balls to move to 2.6.8-rc3. Instead, i took only the via-rhine.c from 2.6.8-rc4-mm1 applied your last patch to it and recompiled the module.

What should i say: It works! I wasn't able to trigger the error with my standard test (copying a 680MB ISO image from/to Samba shares in parallel). An this even with "large readwrite" enabled in smb.conf.

So, i consider this gone - for now :)

(But perhaps you should update the drivers version number)

Thank you very much!

Best regards,

Peter

Odd. AFAIK 2.6.8-rc4-mm1 has all the patches merged. My most recent patch was for mainline only.

Cool. Thanks for the report.

2.6.7 had 1.1.20-2.6. The driver in 2.6.8-rc4-mm1 is 1.2.0-2.6. The driver in 2.6.8 (mainline) is patch-wise somewhere in between but still called 1.1.20-2.6. Ah well.
