At least - moddb may be leaved for user drivers/fresh versions of drivers.
Currently we: 0) probing drivers from initmod 1) trying to probe drivers from moddb 2) trying to probe drivers from sqfs and copy missed drivers to /lib/modules >> 25.07.2015 19:15, kp kirchdoerfer пишет: >>> Hi Andrew; >>> >>> Am Samstag, 4.
