Message-ID: <BANLkTikt+JoeZkHaC1G-=T14n_X9zmoFDQ@mail.gmail.com> Date: Thu, 21 Apr 2011 10:34:41 +0200 From: Daniele Venzano <venza@...wnhat.org> To: cwillu <cwillu@...llu.com> Cc: netdev@...r.kernel.org Subject: Re: sis900 transmit timeouts I do not the sis900 chipset documentation on hand right now, so I cannot decode the TX status numbers. I did not receive any more reports apart from yours and the original one, so it is either a very nasty bug that happens in very particular conditions or an hardware problem. At the time I placed my bets on the 64bit arch because they were rare enough to make the bug difficult to reproduce. I'll let you know if your logs give me some hint. Thanks, Daniele. 2011/4/21 cwillu <cwillu@...llu.com>: > Hi; I'm trying to figure out why the onboard nic on what just became > my primary desktop disconnects for a few seconds every hour or so. > After some googling, I came across the "Transmit timeouts" section of > http://www.brownhat.org/sis900.html, which said to make contact if > anyone sees this.
