Message-ID: <ed364e68730267510d49b2bdc38679a0@gentoo.se> Date: Thu, 21 Mar 2013 14:17:11 +0100 From: peterasplund@...too.se To: Luigi Semenzato <semenzato@...gle.com> Cc: Aaron Lu <aaron.lu@...el.com>, Rajiv Andrade <mail@...jiv.net>, <tpmdd-devel@...ts.sourceforge.net>, <linux-kernel@...r.kernel.org> Subject: Re: [tpmdd-devel] tpm_tis driver failed to suspend, error -62 Hi! Sadly, I have to say that I'm totally oblivious to power-related stuff both in software and hardware, so I have no idea what you are asking or proposing.. :) I don't know if you have access to the files I've included in the bug report, so here are the links to them: https://launchpadlibrarian.net/105830773/lspci.txt https://launchpadlibrarian.net/95994294/AcpiTables.txt https://launchpadlibrarian.net/95994318/BootDmesg.txt https://launchpadlibrarian.net/95994354/UdevDb.txt Regarding the syslog during boot, is that the same as the BootDmesg I've attached? Or should I search in another log file? I'm not sure about the model, but I was hoping you could deduct something from the UdevDb or the lspci output above.
