The beta release of Ubuntu Feisty, the latest release of the popular Linux operating system, has been delayed for a day because of kernel issues. In an email to the Ubuntu developers list last week Tollef Fog Heen wrote: "The beta release [of Feisty] is delayed until Friday due to a kernel regression which caused problems booting on quite a large number of systems.

"A new kernel has been uploaded and built, the same for a new debian-installer. New ISO images are being built and published as I write this mail. DVDs will be re-rolled tomorrow morning since they need new livefs-es built and due to the order we build the ISOs in, they aren't yet."

Heen said final testing of the ISO images would be done on Thursday and the beta release would take place on Friday.
