I usually turn The driver can remember state, yes. It *might* not work though. And it can be overriden by userspace. Do note that when thinkpad-acpi switches bluetoot off, it *disappears* from the bus (so, lsusb won't find it, etc). If bluetooth is still present in the bus, but the bluetooth interface is down, then your problem is not related directly or indirectly to thinkpad-acpi. Now, if the bluetooth state persistence used to work on your thinkpad and it doesn't work anymore, then the problem is likely in userspace. > I don't reboot often, but I remember at one point it was implemented and > working, so I wonder if something is broken here. Well, it *is* possible. But it is more likely that something is turning it on by force at boot. > What do you think? Compile thinkpad-acpi with the Kconfig option "CONFIG_THINKPAD_ACPI_DEBUG" enabled, and pass thinkpad-acpi the module option "debug=0x8004", either through the kernel command line (if it is builtin: thinkpad_acpi.debug=0x8004) or through an "options thinkpad-acpi ..." line in /etc/modprobe.d/*. Make sure you're logging kernel debug messages somewhere (check rsyslog/klogd/syslogd/whatever configuration). After that, do some testing and check the kernel log, thinkpad-acpi will tell you if something tries to manipulate radio state, and it will also tell you when it stores radio state to NVRAM. It should give us some idea of what's happening. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
