--- Comment #5 from Julius Henry Marx (sawb...@gmx.net) --- Hello: Thank you very much for taking the time to write here about this. Much obliged. > ... similar problem ... > ... focus on analyzing what it could be. A thankless endeavour, no doubt. > ... switched ON ACPI_DEBUG ...

The problem with my box (Sun Ultra 24) is that I have never been able to reliably reproduce the fault. It started when I formatted the original HDD and installed Linux on it. Save for the ones that would make the box go absolutely berserk (needing to remove the battery and reset everything back) no change in BIOS settings made any difference whatsoever. Eventually (from one to sixty days) it would rear its ugly head again. In the end I have learned to live with this absolute POS BIOS that Sun Microsystems wrote into an otherwise very well built box, ahead of its time in many respects. But I digress ... The TPM settings in the BIOS have always been set to [Disabled] so I have taken up on your suggestion and changed the TPM settings to [Enabled] according to the instructions here: https://docs.oracle.com/cd/E19591-01/html/E23171/z40013591297501.html What I have not done is reset the TPM as it is [Unowned] as I fear some sort of 'retribution' if I fiddle with that. The only difference is that I now have a TPM related entry in /var/log/dmesg: [code] tpm tpm0: [Hardware Error]: Adjusting reported timeouts: A 750->750000us B 2000->2000000us C 750->750000us D 750->750000us [/code] I now have to wait and see if the fault occurrs again. If and when it does, I will post here again. Once again, thank you for taking the time to write here about this. Best, JHM -- You may reply to this email to add a comment.
