msk msk0 watchdog timeout freeze hang lock stop problem

2015-04-12 Thread Gareth Wyn Roberts

I've run in to problems using the msk device where initially it works well 
enough to set DHCP etc. but stops/freezes as soon as any appreciable network 
traffic occurs . There are several threads describing similar symptoms over the 
past two years or more.  I've been following several false leads but have 
finally found a solution (at least it solves my problem).

I'm running a standard FreeBSD 10.1-RELEASE and the NIC is detected as:

mskc0:  mem 0xfa00-0xfa003fff irq 
19 at device 0.0 on pci6
msk0:  on mskc0
msk0: Ethernet address: 00:13:77:e9:df:eb
miibus0:  on msk0
e1000phy0:  PHY 0 on miibus0
e1000phy0:  none, 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
1000baseT-master, 1000baseT-FDX, 1000baseT-FDX-ma
ster, auto, auto-flow

The network worked when using the i386 release, but failed for the amd64 
release (as reported previously) which prompted me to disable 64-bit DMA (the 
patch for this is attached below).  This worked for the first kernel built but 
mysteriously failed when another unrelated part of the kernel was changed (a 
usb driver) and the kernel recompiled.  So identical msk driver code worked in 
one kernel but not the second! This suggested that alignment differences 
between the two kernels were causing the msk driver to fail. Others have 
reported varying behaviour depending on different circumstances.

It transpires that changing just one value in the if_mskreg.h file solved all 
my problems.  Subsequently I have not been able to make it fail under heavy 
network traffic in either 32-bit or 64-bit mode.
I'm working on 10.1-RELEASE source, i.e. if_msk.c revision 262524 and 
if_mskreg.h revision 264442.

Here's the patch to if_mskreg.h

The patches to both files which also implement a MSK_64BIT_DMA_DISABLE flag are 
attached.  Perhaps the developers would consider committing these as it may be 
useful for future debugging.

Thanks for the suggested fix.

There are five PRs, all describe similar things:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197887
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197002
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=189404
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=186872
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=166727

I added some pointer to your posting, maybe someone can test it ?
