On 2.3.46 I found a similar bug, but I cannot run 'insmod imm' twice
or more time. Now scsi_mod is initilizing, with 2.3.4[45] was ok, but
regarding last bug-report, i see that the error was from scsi_mod (see
EIP).
The bug is in scsi_mod. It is not need the module imm or a ZIP attached,
nor parallel port modules. [modutils-2.3.9]
