Hi Jeff and list, maybe this mail was wrong on the linux-scsi list. So here we go again: -------- Original-Nachricht -------- Betreff: Maybe a bug in libata-core Datum: Fri, 20 Aug 2010 23:48:09 +0200 Von: Stefan Hübner <stefan.huebner@xxxxxxxxxxxxxxxxxx> Antwort an: stefan.huebner@xxxxxxxxxxxxxxxxxx Organisation: TU-Ilmenau An: linux-scsi@xxxxxxxxxxxxxxx Hi List! After sending a WRITE_DMA_FUA_EXT ATA-command via SG_IO Passthru to a harddisk (here: /dev/sdd), my kernel panics. The is what I find in syslog: Aug 20 23:29:49 dobbelherz kernel: ------------[ cut here ]------------ Aug 20 23:29:49 dobbelherz kernel: kernel BUG at drivers/ata/libata-core.c:5136!
