I got a KDL with KERNEL PANIC, meanwhile I clicked on a tab of Webpositive that cjust launched and pages still loading …
fortunately a continue command in the prompt let me continue …
However I started to check syslog, and found the following lines →

Floorp and Streamradio was running and a checkfs for a partition on the boot USB disk, but it was noot the boot partition - that was completed then. And was anotherBFS thumbdrive also only data.
I would like to know the Category and else to open it in a proper way.
Thank you in advance -
