"NETDEV WATCHDOG" problems on IBM Thinkpad T30

[D. Sen]

Hi,

I am using the hostap drivers on my T30 which has a prism2 based pci
card. I am running linux 2.4.20 and the cvs hostap snapshot from Jan 7,
2003. The driver works fine except when I attempt to copy files to/from
a NFS filesystem accross the network. Then I get these errors (sometimes
hanging the machine, requiring a cold-reboot).

Any help will be appreciated.
