Jack BUG: unable to handle kernel NULL pointer dereference at 00000050 IP: [<f8c72778>] setResumeCallBack+0x8/0x20 [agrmodem] *pdpt = 00000000368d4001 *pde = 0000000000000000 Oops: 0000 [#1] SMP last sysfs file: /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq Modules linked in: agrserial agrmodem hfsplus vfat etc ---------- way beyond my skills to work through. Presently I'll test whether one of the Live CDs will support compiling and testing of the drivers with a current kernel.
