NOVA crashes on first LTP test #29

Closed stevenjswanson closed 7 years ago

stevenjswanson commented 7 years ago

Running the first test in the nova set of ltp tests crashes nova.

gf01 growfiles -W gf01 -b -e 1 -u -i 0 -L 20 -w -C 1 -l -I r -T 10 -f glseek20 -S 2 -d $TMPDIR

The Oops or BUG occurs at different places in the kernel, none of them in nova code itself. Maybe memory corruption?

To recreate, install NOVA-ltp, mount NOVA on /mnt/ramdisk then

sudo /opt/ltp/runltp -f nova-fail -d /mnt/ramdisk

Output from console
