Re: [Bluez-devel] a2pd btsco won't compile (FIX) plus xmmserror(trials and tribulations) how cool is this!!! new patch

["Frédéric DALLEAU" <frederic.dalleau@palmsource.com>]

Andrew,

I ran the test you told me, on my computer I noticed the process started =

using 100% cpu time after 35 mins. Two hours later the computer was =

still alive. Certainly an overflow when calculating delays. The relation =

with the freeze is not clear. My only assumption for now is that taking =

so much cpu time can overheat a computer. It should not freeze, but it =

is not excluded. Are you using an overclocked computer? Fan lowering =

software?

The mail thread clearly state the problem is 2.6.17 mh3+ related. If =

you're not already 2.6.17, there is need to try 2.6.16.

I'm isolating the cpu time prob, this is long but easy to reproduce. So =

it should be corrected soon.

Thank you for all your patience :D
