Hello all, While working with my ThinkPad E335 laptop running oi_151a5 yesterday with the wired LAN (Realtek gigabit RGE) plugged in, I noticed that at very regular intervals (20 minutes exactly, according to dmesg) the system locked up and ceased to respond to keyboard/mouse under X11 GUI. I believe the networking also went down, but was not in position to confirm that definitely.
I found that it can remain locked indefinitely (at least for 2-3 minutes), but resumes working within 10 sec after I unplug the LAN cable and "remembers" all the keypresses and mouse jerks. Then I found that the CIFS client also locked it up while trying to download files from a neighboring Windows laptop (after 64-512Kb of transferred data), however it had no problem browsing to the share seconds before that. Perhaps it has to do with some packet sizing which gets hit during bulk file transfers, and the regularity of such lockups without my active intervention suggests that some service may try to use the network every 20 minutes and causes the effect. I do remember that on the first days when I was working with this installation, it was wired for hours and downloaded many gigabytes with no hiccups. Now, I did not use the LAN for a month and many things could have happened to the OS during the time, including installation of VirtualBox with its network driver filters; however unloading these modules did not help. I also updated the TUN/TAP driver to 1.3.0, but modunloading it now did not help either. I don't think I updated the OS more substantially during that time, except for my experiments building AHCI module (HDD is still in IDE mode for stable work) and patching up some SMF service scripts. Ultimately, after about one hour of such intermittent work with no actual usage on my behalf, the LAN interface went down and did not come back up until a full reboot (I did not try fastboot though). I have no idea if this will be reproducible :) Does any of this adventure ring a bell to anyone on the list? NWAM is off, networking setup is static, ipfilter is off (no rules initially, and I also temp-disabled the service while debugging the condition). Nothing in dmesg, except that the rge0 link was going down and up when I plugged it back and forth. Thanks for any suggestions, //Jim Klimov _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
