Wacom Graphire4 A6: SMAP violation

[roiredxsoto]

Good day, Plugging in a Wacom Graphire4 A6 to USB port causes jump to KDL.

This happens with hrev52379 x64 Anyboot (non-EFI) on a Ryzen box: MSI B350M Bazooka Ryzen5 2400G 8GB ram

Plugged into the front USB port which is 3.0, though set to Legacy support inside BIOS.

This issue does not happen at all on hrev52379 x64 on a Sony Vaio VGN-SR19XN, where can plug/unplug and use the tablet without issues. Though Vaio's USB ports are all 2.0.

Thanks Regards, RR

Unfortunately the KDL is cut off, so it's hard to tell what the problem is.

I'll try again and see if there is more and post back, but as far as I know, that image is all that comes out :( Thanks waddlesplash. Regards, RR

The changes to fix the kernel driver look pretty trivial, but I wonder if this is perhaps a good time to get rid of the kernel driver entirely, and let the Wacom input server addon use the USB Kit directly. stippi, maybe you'll have some time to look into this over the next few months?

Same SMAP violation issue occurs on hrev53102 whilst attempting to plug in a Wacom Bamboo tablet.
