Trusted Platform Module[solved - optimistically]
« on: 30. July 2015, 15:47:54 »
Think i have located the source of a few issues i have.

https://en.wikipedia.org/wiki/Trusted_Platform_Module

Looking into whether removal is an option ... without major side effects.
This is worrying also http://www.cs.dartmouth.edu/~pkilab/sparks/

Anyone aware of packages available to bypass/manipulate TPM?
Though implementation of full control with Coreboot(or similar) is something i need to consider.

*
Locked TPM chip:

Too many failed attempts to access the TPM will cause a lockout state for the TPM chip on the motherboard. This is by design of the manufacturer of the TPM.Unlocking the TPM chip requires the machine to be powered on for at least 20 hours continuously. You will need to disable sleep or hibernation in order to allow the continuous time period until the lockout timer expires.The lockout should be less than 24 hours and starts from a few seconds and will grow exponentially depending on the number of access failures

Nice o_0

PS ... https://wiki.archlinux.org/index.php/Trusted_Platform_Module ... the Arch community has an answer for everything ;)

Did you check the BIOS that you have TPM and that it is enabled?

yeah eugen-b ... the BIOS picked it up .... eventually o_0 ... states 'No TPM or TPM has a problem'

i will see how far i get with the Arch TPM packages.
(at present ... none of the AUR packages will compile (whether the binaries are being drawn from sourceforge,may or may not be an issue at this current time).... no matter,i will track down the packages and install manually (maybe a wiser method with this situation?) and currently all my tmp/ permissions for AUR have gone stupid ... so yaourt doesnt know what its doing with the all inode and bitmap errors o_0)


im suspicious that the BIOS needs updating ... however ... flashing BIOS's can often achieve nothing .. or worse case scenario turn your tech into a paperweight o_0

Besides ... its only a matter of time before PhoenixBIOS,TPM and the rest of the badly programmed tat and hardware spyware will BE GONE ;)

Thanks for the tip .. anymoo :)

PS .. im quite impressed with Manjaro's tenacity (even though intermittent) when interfacing with insane hardware ;)
