I just experienced another "sleep of death" on the latest CM7 build.
Luckily I could connect via adb and do a "logcat".
This is what I got: pastebin.com/prGFPNMt
(I cannot post links yet... sorry!)
This is the output from "dmesg": pastebin.com/ARJS66K1
And this from "ps": pastebin.com/jhvXC9ui
At least to me it seems that that "system_server" somehow crashes and effectively turns down the whole system.
Maybe we should get this pastebin-link to the CM7 developers?!
