No but with old style (pre AHCI) IDE it can because the system may MCE if
the CPU<->Disk hangs. If a drive is causing PSU problems it could also
occur I guess - ditto heat. You'd need to decode the MCE

An MCE the hardware can recover from is reported and we continue. CPU
Context Corrupt means the processor internally set a "cannot carry on"
indicator.
