I've suddenly started getting "double fault trap" during DMA
It started to occure after one not so clean reboot of NetBSD. The driver
was working (including DMA) well until that reboot happened.=20
Can be OS corrupted?
There is a part of backtrace:
netbsd: pmap_extract + 0x21
Is there anyone, who can recognize if it happens due to corruption of
I invite any advice with debugging of this situation ...
