Hi, all! On Tue, Aug 22, 2006 at 10:53:13PM +0400, Gleb Smirnoff wrote: > In 5-STABLE the interface up/down events were not logged, either. OK. But what could be a possible explanation for this: em interface, FTPing a large file while putting disk and cpu/memory load on the box -> occasional but easily reproducable complete hangs of network communication (ssh, ping - no reaction). Every time a em0: Missing Tx completion interrupt! is logged. fxp interface, otherwise same setup: no hang after FTPing for hours. General network/bandwidth issues cannot be the cause, because both interfaces were connected to a strictly 100 Mbit/s infrastructure. For the moment I'm not using em interfaces in these systems. I could hook up one to "the net" for someone to log in remotely, if that helps.
