What was the architecture of the host machine that was running that Ubuntu VM? Where are you getting driver 8192cu that is shown in the module list below. If you were using the one that has been built into the kernel since 2008, it would be named rtl8187. I have used that driver extensively on x86 and x86_64 architectures, both in x86 hosts and VirtualBox VMs and I have never seen this problem. --snip-- > Oops: 817 [#1] PREEMPT SMP ARM > Jul 11 06:00:23 raspberrypi kernel: [ 41.753311] Modules linked in: > xt_state iptable_filter ipt_MASQUERADE nf_nat_masquerade_ipv4 > iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat > nf_connt > rack ip_tables x_tables snd_bcm2835 snd_pcm snd_seq snd_seq_device > snd_timer snd arc4 rtl8187 eeprom_93cx6 mac80211 cfg80211 rfkill > 8192cu uio_pdrv_genirq uio Larry
