<DIV><SPAN class=171115819-31122004><FONT face=Arial size=2>Hello
all,</FONT></SPAN></DIV>
<DIV><SPAN class=171115819-31122004><FONT face=Arial

<DIV><SPAN class=171115819-31122004><FONT face=Arial size=2>Over the past few
weeks I've been trying to figure this out, but I'm quite stuck. I'm pretty
new to Linux, so my troubleshooting has only gotten me so
far...</FONT></SPAN></DIV>

<DIV><SPAN class=171115819-31122004><FONT face=Arial size=2>Essentially, the
problem occurs when I try to ftp something at relatively high speeds to or from
my FC3 box. Browsing from the box or other items don't cause this problem,
as they don't get the bandwidth that apparently triggers this problem.
When I start my FTP, things go smoothly for a few moments (say they're running
at 10MB/sec), and then the machine dies (no response, although the lights on the
keyboard are not flashing).</FONT></SPAN></DIV>

<DIV><SPAN class=171115819-31122004><FONT face=Arial size=2>I had been convinced
it was a network card problem, so I swapped my old car out and put in a dlink
DGE-530T (gigabit), but got the same results. I changed the DMA settings
on my drives and, if I disable DMA, the crash does not occur - it's only
transferring at a few MB/sec then (like 2MB/sec). Enabling DMA, but at a
lower speed (say ATA/66) causes my ssh session to lock up, but I can continue to
use the box, and I got some of the crash output in my dmesg (attached). I
noticed a line that said something about IRQ and thought possibly my network
card doing something funky with memory, so I enabled IRQ_Moderation on my
network card.</FONT></SPAN></DIV>

<DIV><SPAN class=171115819-31122004><FONT face=Arial size=2>Trying the same
experiment of transferring a file (but with the mod on now), I got another crash
on the current SSH session, but checking dmesg, I got a slightly different
error. Perhaps it's the same thing, but I'm not experienced enough to tell
:( I've attached this log as well.</FONT></SPAN></DIV>

<DIV><SPAN class=171115819-31122004><FONT face=Arial size=2>I don't think
anything looks out of the ordinary in there, so I'm really stumped.
Turning off DMA isn't much of an option on this box as I run MythTV on it and
need good drive bandwidth.</FONT></SPAN></DIV>
