I'm having this issue as well. I have an Asus P5K-E motherboard. Running Gutsy 7.10 (kernel 2.6.22.-16). It appeared to happen out of nowhere 2 days ago. I disabled the JMicron chipset on the motherboard and the messages have gone away.
It might just be a coincidence, but my interest was piqed by the above suggestion that there may be power supply issues. My computer seemed to hum louder than normal. I opened up the case and discovered the main case fan was not spinning (and therefore the CPU fan was working harder). As soon as I opened the case I heard the CPU fan speed start to go down. SOOO, its possible that: A) The JMicron chips are sensitive to heat? I had no problem for the last 10 months or so, and this just came on. No hardware config change, and no major software changes I'm aware of. B) Maybe my power supply is dying and the plug I was using to power the fan was just the first one to go...not sure if that makes sense. -- Jmicron AHCI controller probs... https://bugs.launchpad.net/bugs/198871 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
