Hi there, We have a bunch of Fujitsu-Siemens Futro A255 thin clients[1] which wont play nicely with our LTSP-5 system. We sent a problem report to Fujitsu-Siemens and got the expected answer - they wont help us because we're not running eLUX NG or Windows CE.net operating system... Hopefully someone here can help us.
Here's the <problem_report>: We are running an LTSP-5 system on Debian 5.0 (Lenny) using KDE as the window manager. Only notable change we have made to the default setup provided by Debian is that we are using XDMCP instead of SSH. Problem with our Futro A255 thin clients is that they start to freeze randomly one by one when they are under use. By freezing I mean that the client becomes totally unresponsive and the display freezes. Sometimes the first freezing occurs within minutes after log in and sometimes it takes ~10 minutes or so. Some of them might last for an hour or two but usually eventually they all end up dead. In the meanwhile there are four clients that are built from spare parts that have been running smoothly for 27 days now. Sometimes a client writes an occasional "nfs: server <our_server_ip> not responding, still trying" appears to syslog moments before and sometimes - very rarely though - a few minutes after the client freezes. Sometimes there is also a "NETDEV WATCHDOG: eth0: transmit timed out" message which might or might not be related to the problem. We have been doing a lot of testing and we think that the ethernet driver (r8169) might be the culprit. We have tried to use different kernel versions (2.6.26-1-486 and 2.6.26-2-486 provided by Debian and 2.6.29.4 from kernel.org) with the in-kernel driver and the driver from Fujitsu-Siemens website. Other tests we've done include but are not limited to disabling ACPI, APM and apic, upgrading X.org display drivers, using different swithes between the server and the clients, etc... </problem_report> The provided eLux NG operating system runs on Linux kernel 2.4.32 and uses r1000 -module as the ethernet driver. Source for r1000 can be downloaded from the Fujitsu-Siemens website and AFAIK it has been merged with the r8169 driver which comes with the stock kernel. Anyway the r1000 doesn't work with a 2.6 kernel. We propably wont have the chance to do any more tests with the clients before July, but any ideas that we could try then are welcome. 1. http://ts.fujitsu.com/products/deskbound/thin_clients/futro_a.html Regards, Eero Lemmelä ------------------------------------------------------------------------------ Are you an open source citizen?
