Netdev watchdog timed out on gianfar ethernet driver

Hi , We are using gianfar ethernet driver in our device (2.6.20 kernel). I have observed the following error after i run high throughput traffic for some time. NETDEV WATCHDOG: eth0: transmit timed out The Kernel we are using is 2.6.20 kernel. I have added the work queue support in the

No userspace processes scheduled for execution when ethernet link state changes

Hi List, I am using linux 2.6.22 on a MPC8358E custom board. I use a simple userspace process that periodically (100 ms) calls an ioctl to a watchdog driver to toggle its pin state. The problem is that when I insert or remove the Ethernet cable, this process is not scheduled for execution. The

Big file copy problem

Hello, I found out this strange behavior on my system. I’m working on an embedded device with a linux kernel 2.6.24.6, we’re using a modified Ångström distribution with BusyBox v1.13.2 I’m having problem when I try to copy files larger than 52 Megabytes. The system hangs and I have a kernel

Ethernet support missing p1020rdb.dts

Hi, I've just noticed that ethernet nodes are missing in p1020rdb device tree. Are there any known problems with ethernet controllers on p1020rdb ? Thanks. Felix. ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org

[PATCH 1/2] net: ll_temac: remove virt_to_bus call

The virt_to_bus call should not be used any longer as it's considered illegal. The driver has the physical address of the buffer in the descriptor such that it's not necessary anyway. Signed-off-by: John Linn john.l...@xilinx.com --- drivers/net/ll_temac_main.c |4 +--- 1 files changed, 1

[PATCH 2/2] [V5] Add non-Virtex5 support for LL TEMAC driver

This patch adds support for using the LL TEMAC Ethernet driver on non-Virtex 5 platforms by adding support for accessing the Soft DMA registers as if they were memory mapped instead of solely through the DCR's (available on the Virtex 5). The patch also updates the driver so that it runs on the

Re: Question regarding the DTLB Miss exceptions

When a DTLB Miss exception can't find a PTE for the virtual address being written/read, it dummies up the SPRs for a DSI exception and then calls directly into the DSI exception code. Just before the DTLB miss code stores a value into DSISR it sets bit 2, which for a DSI exception is

Upgrade to 2.6.26 results in Oops during request_irq

Howdy All, I have (almost) successfully upgraded from Linux 2.6.22 to 2.6.26 (both downloaded from debian) on my mpc8347 powerpc, but I think I may be missing a required change to my dts regarding the IPIC or maybe a change in how my driver requests IRQs. I have several modules that are
