bus-master DMA error (was: stability of Cobalt Qube 2)

Hi,

I don't care if it's slow, as long as it works :)
I installed the Qube using the 5.1.2 restore cd (which is very easy) and this installs the netbsd-INSTALL kernel. Could it be that I should be using the netbsd-GENERIC kernel? What kernel (config) are you using, since my setup seems less exotic than yours and yours is working just fine? How can I enable the netbsd-GENERIC kernel?

Sorry for my stupid questions, I am a longtime Linux user taking my first steps in BSD land :(


regards,

Kenneth

Hi

I have a Qube 2 which I use as web/ftp/media/samba server with 3 drives (10x2.5", 160x2.5" and 750x3.5") and 256 mb of ram running 5.1 generic with an aftermarket psu  and I can also say that it is stable but very slow on network transfers, I fixed previous stability issues using cron to reboot the system every month, before that stayed up with maximum uptime of 170+ days before it crashed.

Network as I said before is slow, I use the 750  gb as a backup for 6 computers/laptops and it takes some time but at the end it does his job.

For what I need the qube does a very good job, hope you can fix your issues.

Regards.

All,

Thank you for your answers. My setup is as follows (you can also see this in images on http://kennywest.blogspot.com/2010/02/story-of-cobalt-qube.html):
- one CF to IDE adapter (containing NetBSD base install), master
- one 320 GB hard drive containing some Linux partitions, slave

Base install went like a breeze and it boots fine (320 GB drive disconnected). But, whenever I connect the 320 GB drive, I get this:
VIA Technologies VT83C572 USB Controller (USB serial bus, revision 0x02) at pci0 dev 9 function 2 not configured

this goes on and after some time it finally boots to a login prompt.

Does someone have an idea what this means?
(please note, above setup boots fine and without any errors in Debian Squeeze)

Kenneth

I want to use this as a NAS device for backing up various Linux machines on the network (I want to do this using mondo over NFS). Apparently this proves more difficult than I thought (see also: http://lists.debian.org/debian-mips/2012/03/msg00015.html). Seems the Qube 2 dies under heavy network load. So whenever mondo tries to upload the restore images to the NFS server, it starts to hang. Also tried using a newer network card (since there is a free PCI slot anyway), still the same issue.

My experience with the Qube2 is that it's very stable with NetBSD, but not fast for I/O. There was some issue with the PCI bus which impacted performance. If you search this list far enough back, you might find the details.

I used mine for small jobs like DHCP server, internet gateway/firewall, and some other menial stuff until I got a Seagate Dockstar, which I use now. The Dockstar has it's issues with NetBSD as well.
