Subject: IDE corruption during heavy bt878-induced interrupt load
Date: Tue, 22 Apr 2003 14:45:14 -0400 [thread overview]
Message-ID: <200304221445.14656.jbriggs@briggsmedia.com> (raw)
I am seeking comments or suggestions to this problem:
I create multi-channel digital surveillance systems using cards with 4 or more
multiplexed bt878 framegrabbers; each one capturing 5 or more frames per
second on each of its two input channels (total 4 * 2 * 5 = 40 fps).
Typically I run using either a Promise or Adaptec HPT370 IDE-RAID controller
with 2 WD-120GB/8MB-cache drives striped in RAID-0, with another IDE as hda
for my system drive. What happens is that every few seconds I get a "BTTV:
RISC ERROR - resetting" from the frame grabber driver. After a few days of
this I have corruption on my Reiser file system; which usually I am able to
clean up with mkreiserfs --fix-fixable or --rebuild-tree. The corruption is
both on my RAID and my system drive. Missing doing this maintenance action
can really ruin my day.
I am today replacing the IDE RAID with a 3WARE IDE-RAID that emulates SCSI on
the premise that the problem has to do with hardware bus arbitration. But as
of yet I don't have any data to support that or show improvement.
All comments/suggestions/etc. appreciated.
Joe
