Perhaps mtd_kmalloc_up_to() should be including __GFP_NOWARN in its final kmalloc attemot, but that won't help you. As for why the mount actually fails I cannot say - hopefully the fs isn't dependent upon the success of an order-5 page allocation? |
Created attachment 137081 [details] Mount Error Logs Hello Friends, I am mounting configuration partition(NAND) during firmware upgrade and commit operations. And some times, I am getting error of mount failure and some of logs in syslog and dmesg(attached). So how to resolve this issue? PFA.
