Hi list, I just (2011-04-19) upgraded to the current media_build with build.sh commit bcfdefe9f4538abf12fca1cdb631c80e3d598026 Author: Mauro Carvalho Chehab <mchehab@nehalem.(none)> Date: Sun Apr 17 08:21:25 2011 -0300 and hit a problem. I have an Antec case with an LCD screen. It needs the imon driver. The LCD screen has been working well using media_build from 2011-01-30. The imon kernel module now spews this at a high rate: [ 38.532581] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.544545] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.552548] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.560560] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.568546] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.576557] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.584554] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.592558] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.600533] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.608551] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.620024] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.636034] imon 9-1:1.0: lcd_write: write 8 bytes to LCD [ 38.652034] imon 9-1:1.0: lcd_write: write 8 bytes to LCD If I stop LCDd # /etc/init.d/LCDd stop the spew stops.

Can anyone shed light on why the module is spewing to dmesg, and what should I do to fix it ?
