So uhci, radeon, and em2 (which can be sky2 or e1000 driver) generate spurious interrupts. Most suspicious is network device driver for em2 network device. Can you reproduce this problem somehow? If so, can you blacklist sky2 module (or e1000), and see if the problem gone. i'm not sure how to black list modules, but it seems as though the problem has gone away, i've done a few updates since then so.... maybe...... i do have an older radeon card in the box, maybe that has something to do with those interrupts. Blacklisting module is done by adding "blacklist module" entry into a /etc/modprobe.d/blacklist.conf . Ok, since the problem does not happen any longer I'm closing bug report. If it come back just reopen this bug report. |
