Keyboard/mouse failure with ACPI
« on: November 21, 2013, 09:14:30 AM »
Hi All,

When using ACPI, the RSDT table will be corrupted by TINYCORE. Then the keyboard and mouse will not work. Either the PS2 or USB devices. It seems to be a timing problem, as sometimes the RSDT table is not destroyed and then everything will work. As the ACPI data is in reclaimable memory, I suspect it's reused accidentally by TINYCORE before the ACPI driver has finished it's processing.

I have seen that a lot of people having trouble with the mouse and keyboard with ACPI and thus turns it off by acpi=off. Finding the cause of why it's doesn't work would be far better and in my experience it seems to be an entire timing dependent failure. It appears to be totally random for different boards/computers.

Best regards,

This isn't really enough to go on: what version of TC, what component (kernel? X?)?

We have one report of this before, on TC 3 (two major versions back): http://forum.tinycorelinux.net/index.php?topic=10731.0
