This one occurs in my regular (HD not boot floppy) kernel bootup, seemingly
only when it has to fsck the drive (ext2). I have the USB drivers configured
into the kernel (UHCI, /proc/bus/usb, USB devfs, USB scanner). It is
not fatal.
ksymoops 0.7c on i686 2.3.39. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.39/ (default)
-m /boot/System.map (specified)
No modules in ksyms, skipping objects
Unable to handle kernel NULL pointer dereference at virtual address 00000005
