I can't parse that sentence above. I will explain: 1. I have compiled kernel with LOG level 7. 2. You have mentioned to run with "log_buf_len=10M ignore_loglevel". When I ran, the Error messages started splashing continuously, I waited for 5 mins and tried to switch modes using Ctrl+alt+F1, no use. 3. The one I attached dmesg is only log_buf_len=500M (no ignore_loglevel). > > ignore_loglevel is another kernel cmdline parameter: > > ignore_loglevel [KNL] > Ignore loglevel setting - this will print /all/ > kernel messages to the console.
