Subject: [4.8.0-rc1] am335x-evm boot failure: n_tty_receive_buf_common:
"Unable to handle kernel paging request.."
Hi All,
I've run nfs-boot stress test (1000 iteration) with Kernel 4.8.0-rc1
it has been failed ~25 times with "Unable to handle kernel paging request at virtual address 00002244"
triggered form n_tty_receive_buf_common().
config: omap2plus_defconfig
Log is below. Any thoughts? Is it smth. known?
