Hi,
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.
