For what it's worth, I have tested Linus's patch on my ARM Chromebook (which was reproducing the divide by 0 yesterday). With the patch the system has no divide by 0 and still boots fine. Interestingly enough the divide by 0 appeared to happen at probe time once for each partition of both the internal eMMC and the external SD card. Later in the boot sequence the code runs with a non-zero discard. I'm not familiar enough with this part of the kernel to speculate why this system behaves differently than the systems that Jens tested on. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
