[Voyage-linux] Re: v0.6 on WRAP - dma errors

[Dylan Hall]

That seems to work nicely :)

I've used "dpkg -i" to install the new kernel and aufs modules. I don't
use wifi so no madwifi updates required.

I've commented out the /etc/modprobe.d/ bits that passed the ide=nodma
options to the ide_core module.

I've rebuilt the initrd to ensure the above changes are actually used.

Rebooted, confirmed issue with DMA occurs (DMA errors probing the ide
controllers/disks, eventually gives up and disables DMA automatically).

Rebooted again, this time feeding "ide=nodma" to the kernel from grub.

No issues during start up :)


Can I assume this or a similar kernel will make it into the repositories
shortly so a simple "apt-get update; apt-get upgrade" would have the
same affect?


Thanks for your efforts, much appreciated :)

Dylan
