Yes, but without knowing the error put in errno by shmget(), it's difficult to say why it failed. > shmget(4096, 4096, IPC_CREAT|0x1b6|0666) = -1 EINVAL (Invalid argument) strace shows that error EINVAL was returned. > I tried putting printk() in do_shmat(), sys_shmget(), shm_init() in > ipc/shm.c.

Can you print the call ID on entry, and put a printk() by each error return so that you can tell which it returns through?
