Hello Oliver, > UMTS draws more power than GPRS. > For some more debugging concerning deadlocks you can > compile with CONFIG_LOCKDEP_SUPPORT=y. http://groups.google.com/group/linux.kernel/browse_thread/thread/c558616bc45ffcc0/3d18a969a7e5dc62?lnk=raot This seems maybe the same issue, but the system only freezes there. CONFIG_LOCKDEP_SUPPORT seems to be activated by default in openSuSE kernels. > But this looks like an overstressed battery. Yes. But why does this happens only under Linux ;)?
