I can confirm this one. It happens to me during the init_floppy call
when the init_scsi has not yet taken place - so the swapper is not yet
able to fulfill any paging requests(?). The ksymoops output however
does not seem to make any sense here. Note that I do only have SCSI
and no IDE devices which are initialized before the init_floppy call.
