modprobe: page allocation failure
Closed this issue · 2 comments
After kernel compilation i get his message while booting up:
EXT4-fs (mmcblk0p2): re-mounted. Opts: (null)
vmalloc: allocation failure: 0 bytes
modprobe: page allocation failure: order:0, mode:0xd0

RPi seems to work normally, but it would be nice to know what causes this failure.
Thx and best regards,

I've enabled kobject debugging, maybe its helpfull:

Best,

Sadly your backtraces are useless as they don't include any function names, but your kobject debugging seems to point at the snd_bcm2835 driver. Do you have this compiled-in or as a module? This isn't a driver I've looked at before so I don't really have any idea about what might cause this.
