Hi, First, thank you all for being so diligent. The unsolicited packet problem seems to have been resolved. However, by running gscanbus, then unplugging a camera and replugging it in, I got the following oops: Unable to handle kernel paging request at virtual address 08103a8c printing eip: 402fd1de *pde = 07b1c067 *pte = 00000000 Oops: 0006 [#1] CPU: 0 EIP: 0073:[<402fd1de>] Not tainted EFLAGS: 00010202 EIP is at 0x402fd1de eax: 00001579 ebx: 4039ff60 ecx: 00001009 edx: 08103a88 esi: 00000004 edi: 00000000 ebp: bfffc788 esp: bfffc760 ds: 007b es: 007b ss: 007b Process gscanbus (pid: 2525, threadinfo=c2314000 task=dc4af000) <6>note: gscanbus[2525] exited with preempt_count 1 ----------- Ok, you'll have to forgive me here, as I've never used ksymoops before, but here is my attempt: ksymoops 2.4.8 on i686 2.6.0-test1-ac1.

Since I see the preempt bit above, I'll try compiling without a preemtible kernel and will report the results tomorrow.
