Description Mario 2006-10-14 06:35:19 EDT
Description of problem:
System hangs when I tries to backup discs attached on IT8212 raid controller.
With other discs, on other controllers, it does not happening! I have tried with
dump, tar, cpio, but it always hangs. Other ways I have not have any problems
with this disc and controller or any other disc or controller. Under Windows XP
(dual boot) there is not problem with backup or any other operation.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. dump -0 -b 64 -M -B 524288 -j9 -A opt.dumplog -f opt /opt

Expected results:

Comment 2 Alan Cox 2006-10-15 10:26:26 EDT
To debug this need the actual messages from the IDE controller printed on the
console as it chokes. I would suspect you have one of the firmware versions that
dies under very high I/O load, in which case there isn't much that can be done
except to put the controller into non-raid mode with the it8212_noraid option.

Comment 3 Jindrich Novy 2006-10-24 08:13:37 EDT
So is there needed to fix something on the dump side? It sounds more like a
hardware issue to me.
Comment 4 Alan Cox 2006-10-24 10:33:10 EDT
Dump causes long streaming I/O patterns which seem to blow up some of the
firmware versions. Hacking the ide driver to limit its maximum I/O size might
help a bit but its certainly not a dump problem.
Comment 5 Dave Jones 2006-11-20 16:17:03 EST
Mario, can you try and capture the messages Alan refers to in comment #2, and
also separately, try the it8212_noraid option ? Thanks.
