Default Request for assistance with a bug

Apologies for this long message in advance



Accepted.



Thanks in advance for any assistance or advice!



Advice

Use less history, and use more details. In your first paragraph you wrote that
you can't seem to get any dev's interested in your issue. I would leave that out
entirely. Instead, I would have mentioned what Desktop Environment I use, what
version, kernel, etc.


If you are using gnome, I would suggest trying to open up a ticket on the gnome
development bug tracking system.


This is just a guess, but Lenny just went into feature freeze and they decided
not to use the new gnome files transfer sub-system in Lenny. Therefore, I would
guess that since you're using Hardy (that's a guess too actually), which uses
the new gnome file transfer system, Debian dev's are going to have their hands
full with lenny stuff and won't be jumping all over your problem until they
start looking at it themselves for lenny +1.


My advice is to create a separate partition, install Ibex and file bug reports
against Ibex. That is your best bet (IMHO) to getting this issue resolved in the
next 6 months.


Or, install Lenny, which won't be using the new gnome VFS transfer
thing-a-ma-bobber, and so probably doesn't have this issue.


Good luck!

What you haven't said here but have said on the launchpad bug is that
the issue is specific to nautilus / gvfs. Have you reported it
upstream as Sebastian suggested?

I have had similar problems with usb transfers in the past, one on an external hdd (seagate - there are other problems there such as disk spindown and how the firmware responds afterwards that make it of little use for this test) also a 1GB mp3player which after a few songs transfered the connection drops to a crawl

on my system (looking at the output of top and atop suggests a high degree of swapping going on during transfers, especially if other actions are being preformed at the same time. if this is a part of the problem I cannot say, just that it seems to be in my case. (cpu usage is almost 0 but swapping is going on like crazy. I would wonder if it closer to a paging error if that is the case

also thought check out
https://bugzilla.novell.com/show_bug.cgi?id=105871
seems to be in the sync flag on the new kernels (if i am reading it correctly) and also suggests fixes, it may help

If you can't reproduce it what can you do?

In the kernel bootup messages:

root@box:/var/cache/apt/archives# dmesg | grep pci=routeirq
[ 0.448613] PCI: If a device doesn't work, try "pci=routeirq". If it helps, post a report

Although it doesn't say where to post the report. :-(
