Re: [ts-7000] General Reliability of 2.6.21 on TS7800

[Jeremy Freeman <>]

When I talked to support at TS they acknowledged that they knew of other customers having similar issues but had no solution in place.

It's pretty easy to reproduce this lockup, all you have to do is have high serial and SD card IO at the same time. And eventually things will come to a grinding halt. One of the following will occur:

1) Any process that has to write to SD card will completed hang. Cannot kill it in any way. Only a reboot will clear this condition.
2) All reads will lock up preventing any kind of access.

We have managed to keep our application running by logging everything to ramdisk; this has made lockups much less frequent. If a lock does occur, our app will continue to run as it does not rely at all on SD card for writes.
I have tried JFS, ext3, ext2 all with the same result. There is lots of memory available and that is not the issue.

I would love a solution to this so I can sleep more comfortably at night with the 7800s I have installed in dark far away places around the world.

Would be great to get an official word form the TS guys about this ...

Are we 100% sure it's only related to SD card access ?
