Date: Tue, 29 Dec 2009 13:00:05 -0500 From: Nick Bowler <nbowler@...iptictech.com> To: Alan Cox <alan@...ux.intel.com>, linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...e.de> Subject: [Regression, bisected] Receive failure in et131x. Continuing the theme from the last release cycle -- my PCI-express et131x card (which works in 2.6.32) fails in the latest Linus git. The card works at first (DHCP and NFS mounts during bootup are OK) but quickly fails once any reasonable traffic is put through it. Transmit seems to continue to work after a failure, but receive is mostly dead forever -- the occasional frame appears to make it through. The kernel log contains many messages of the following form: et131x 0000:02:00.0: NICRxPkts PSR Entry 1546 indicates length of 12920 and/or bad bi(614) et131x 0000:02:00.0: NICRxPkts PSR Entry 1547 indicates length of 27745 and/or bad bi(92) et131x 0000:02:00.0: NICRxPkts PSR Entry 1548 indicates length of 30064 and/or bad bi(116) ... Bisection reveals the following. 99fd99f618daecae638550275cb132ab1ffe464c is the first bad commit commit 99fd99f618daecae638550275cb132ab1ffe464c Author: Alan Cox <alan@...ux.intel.com> Date: Wed Nov 18 14:07:58 2009 +0000 Staging: et131x: clean up the avail fields in the rx registers These have a wrap bit but again need little work to clean out. There are a couple of uglies left that want addressing in later clean up. Notably we should probably keep the local psr copy and wrap as two values.
