eMMC error -110 and high priority processus

Djey1301

Hello,

i've a question about some errors on internal eMMC on embedded linux 3.14 (IMX6 arm processor).

I can observe that if i have some bigs apps on nice -20 on the system, on power loss, i have error -110 on eMMC.

It can corrupt definitly the OS, and i cant boot. Its a embedded device with no APM, no reboot/shutdown button.

You just disconnect the power.

It can be really the reason of errors (nice -20) ? Or just a result ?

Where i must look for ? Driver ? Kernel HW patch ?
