This kernel dumps uncompressed dmesg blobs into pstore and gets them back out again. So it seems likely that the problems are someplace in the compression/decompression code. -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
