i'm experiencing this bug with my "ACER Aspire Easystore H340" running ubuntu natty.
this happens after the box switches to UP code (i do not know if this is actually related, but i notice that it *always* happens after the switch). please find the syslog file attached. cheers, raoul excerpt from /var/log/syslog: Apr 9 12:12:53 media kernel: [ 2356.741312] CPU 1 is now offline Apr 9 12:12:53 media kernel: [ 2356.741323] SMP alternatives: switching to UP code Apr 9 12:12:54 media kernel: [ 2357.383713] EXT4-fs (sda1): re-mounted.
