DMA lockup on Cron


Hi, im using Slackware 10 and seem to be having a problem with DMA timeouts on the 4am cron which is locking the machine solid.
Any ideas please?

Hi, and welcome to LQ!

And first we need more info.
What motherboard are you using, what job(s)
are happening at 4am, can you post a few of
the errors you're getting, what kernel do you use?

Generic guide - most helpful!



Cheers,
Tink

The 4am "thing" is slocate updatedb i think,
The machine just locks solid and takes a couple of cold boots to get going again, as resetting dosnt work, it gets stuck on "DMA timeout"
Hope this info is ok

Much better ...


Does that problem also occur with the stock-2.4.26
kernel that came with slack?

Can you somehow check which drives it happens
with? I recall (from browsing here, not from experience)
that there's quite a few problems with the promise
controllers....

You could, for example, make a test-run and tar
stuff from all mount-points that live on separate drives
individually onto one drive.


Cheers,
Tink
