I changed to # grep CONFIG_SYSFS .config CONFIG_SYSFS_DEPRECATED=y CONFIG_SYSFS_DEPRECATED_V2=y CONFIG_SYSFS=y and re-bisected. Now it turned out that 39aba963 "driver core: remove CONFIG_SYSFS_DEPRECATED_V2 but keep it for block devices" is the commit which caused these error messages. Guessing from error messages, changes in drivers/scsi/hosts.c and drivers/scsi/scsi_scan.c might be involved. > Other than that, everything works ok, right? Right.
