I had this problem on my eeepc 1201 ION on karmic ubuntu (2.6.31-17-generic).
I upgrade to 2.6.33-020633rc4-generic with the NVIDIA-Linux-x86_64-195.30-pkg2.run nividia drivers.
I submitted my netbook to highload (I found out that the freeze occured mostly on heavy hdd access )
Several hours after .. still no freeze ... seems i's fixed .. I'll repost a feed-back in 3-4 days .
