working the bugs out of a Sony GRX650 - interrupts and the sound card

[Hrant Dadivanyan]

Hi Stuart,

You also should have difficulties with memory stick, second PC card slot
and sometimes USB, correct ?  AFAIK, Sony GRX and GR series have the same
issue with interrupts delivery, when no interrupts are received by driver.
vmstat -i should confirm it.

I own GR300 and after two years fight found a workaround to get at least
sound to work with STABLE - since video and sound share the same irq 9 as
almost everything in this Sony design, if you configure kernel and X to
use DRI (http://people.freebsd.org/~anholt/dri/), it will produce enough
interrupts the sound to work well.

Two weeks ago I have installed CURRENT and found that everything works
pretty well in generic install. Also during these days CURRENT looks much
stable with my laptop than STABLE. Thanks to all people working on FreeBSD !

Hope it help you,
Hrant
