Herbert tells me that returning NETDEV_TX_BUSY from hard_start_xmit is seen as a poor thing to do; we should cache the packet and stop the queue.

Hi, Is netconsole supposed to work under pvops? When I try to enable it I get the following: Initialising Xen virtual ethernet driver. blkfront: xvda1: barriers enabled netconsole: local port 11111 netconsole: local IP 10.20.40.2 netconsole: interface eth1 netconsole: remote port 9514 netconsole: remote IP 10.20.50.2 netconsole: remote ethernet address 00:16:3e:00:50:02 netconsole: eth1

I'm supporting a number of consumer devices (e.g. small NAS devices) in Debian. They typically don't export the serial console and don't have any other output devices. We perform the installation via SSH on such devices and start SSH automatically when the system boots so people can login. This works pretty well but sometimes a device stops to boot for no good reason. This is

Appologies in advance if there is an obvious answer to this. I'm experimenting with netconsole. When I try to insmod the netconsole module it complains that eth0 doesn't support polling. Any idea where I can find a list of supported NICs? How can I workout if a NIC driver supports polling? Many thanks Daveh

Hi, I'm in the position that a network console would occasionally be very useful for me to control pxelinux. Has the possibility of adding it (next to VGA and serial) been ever discussed? I understand that it may sound somewhat contorted, but it could also serve instead of a TFTP PUT for extracting hardware info, for example... How hard would it be to add (considering gPXE as well)? --
