This is possibly not the Intel firmware bug mentioned in my previous comment but an older one:
X18/X25-M/V G2 series with Firmware before 2CV102J8 may hang if self-test log is read. G1 series may also be affected. Smartctl and smartd print a related warning for G2 series but not for G1.

Please update the SSD firmware if possible.
