[Bluez-devel] system freeze in 2.6.17-mh5

[Stefan Maintz <stefanmaintz@gmx.de>]

Hi there,
I am using gentoo linux and recently updated my kernel to
gentoo-sources-2.6.17-r4 and patched it with the -mh5 patches from
bluez.org. I need this patch for getting my Logitech Dinovo desktop to
work.
After upgrading I discovered that my machine freezes after being left
idle for approximately 30 min.
I posted this problem already at forums.gentoo.org and someone
suggested me to remove the bluez-patch and see whether the problem
still occurs and it does not without the patch. This makes me think
that the system crash must somehow be related to your patch.
The console log of the crash is as follows:

I can post any config-files as needed and I am willing to support the
debugging if told how to.
Thanks in advance,
Stefan

PS: I cannot post again between Thursday and Sunday, I'm sorry.
