Hi,
I am using 2.4.16 with xfs patch from SGI. It may not be the acenic driver problem, I can reproduce the deadlock in a 100 base-T network using eepro100 driver. Closing the server did not release the deadlock. What else can I try?

Hi,
What kernel version are you using ? I suspect that its not the ethernet driver causing this deadlock. Am I right in thinking that if you kill the nbd server process that the hanging process is released ?
