Compiling and installing r4294 (before this I used r4051) I came across a 
problem with flashfs:
[root@asus-router root]$ flashfs commit
/dev/mtd/4: No such file or directory
[root@asus-router root]$ ls -la /dev/mtd/

Historically, flashfs grows from down to top of physical flash. It was simply 
overwritten by firmware due to size increase. Just restore flashfs from backup.

Okay, how can I restore flash if i can not take access to device in which flash 
must locate?

Works for me.

Such situation can be happened only if your customized FW image are too large 
to has free space for flashfs.

Thanks a lot, only question - how to calculate free space for flashfs after, 
say, making new firmware? Or maybe that question preferable for forum, not 
issues list? =)

total flash size = CFE + nvram + FW + flashfs(min 64K)

эта ошибка возникает когда или повторно 
или еще как то применяются патчи на ядро

нужно удалить сорсы ядра - потом заново 
скопировать и один раз применить патчи
