entries in "ps"

Hi list! I found some entries in "ps" on one of my boxen.. I am quite sure this is normal behaviour and nothing to worry about; however I'd like to have this conclusion confirmed by someone who actually knows what he/she 's doing ;-) The Box is a SuSE 7.2, running patched kernel 2.2.19 The ps output contains these two entries im concerned about: 9 ? SW 0:00 [scsi_eh_0] 10 ? SW 0:00 [scsi_eh_1] are those SCSI modules or something? TIA Chris Burri .-. /v\ L I N U X // \\ >I know KungFu!!< /( )\ ^^-^^
