Ad-hoc network -> out of sw-iommu space

krey · 2012-01-23 15:35:59

When I run my create ad-hoc network script, things work fine for a while, then suddenly the machine goes crazy with errors of the form:

Jan 22 19:51:55 localhost kernel: [15434.481982] DMA: Out of SW-IOMMU space for 77 bytes at device 0000:08:00.0
(this is my wireless card)

then after a hundred of those, I start getting

Jan 22 19:52:01 localhost kernel: [15439.609268] DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:00:1d.0
(this is a usb external hard-drive)

and then there's hundreds of thousands of lines of that (literally: kernel.log, errors.log are now 13.2 GB)

Also, my computer dies and requires a manual reboot once these errors manifest.

Here are the relevant parts of lspci -vv:

and here's my ad-hoc script:

I would be grateful for any kinf of help regarding this!
