Sorry for the top-post, but I'm sending this from my blackberry, which has its own agenda apparently.

If by the statement about video you've noticed the desktop seem to 'flicker' and redraw the icons, then I've seen it too. I upgraded kubuntu 7.04 from 2.6.16 to 2.6.20 recently.  I've also noticed the usb problem, but I've also noticed that my wireless now has intermittent problems and the wireless icon that shows signal strength when connected no longer appears.

Subject: BAAAAAD problem with Feisty kernel

Aside from ferm appearing out of nowhere and clamping down all services but SSH, my Feisty "upgrade" has done something really anti-social.  Basically I was seeing Feisty reset video (and sometimes sending it into a tizzy) every few minutes.  It took me a while to also notice that it was shutting down my external USB disk and, upon further investigation, the SATA disk subsystem too.  If I left it alone long enough it would eventually freeze the whole system dead.

Luckily this was an upgrade, not a new install, so when next I booted, I brought up the last kernel Edgy gave me (.17 instead of .20).  My system has been solid as a rock ever since.

Something bad has happened in the transition from 2.6.17 to 2.6.20.  How does one start going about characterizing this enough to report bugs and who bothers to listen to end-user bug reports in the kernel development team?
