* Karel Zak <kzak@xxxxxxxxxx>: | There is a bug in the new dmesg(1) code, affected are systems without | CONFIG_PRINTK_TIME and maybe some very old systems with kernel <= 2.6.16. | The problem is that dmesg incorrectly works with empty lines (e.g. "<6>\n"). After patching dmesg, there is still difference between the old 2.19.x and the new 2.20 output. Is that normal?
