Hi, After upstream commit 4e6c82b3614a18740ef63109d58743a359266daf ([SCSI] fix WARNING: at drivers/scsi/scsi_lib.c:1704), which is also included in 3.0-stable and 3.1-stable kernels, the kernel fails to boot (NULL pointer dereference in sym53c8xx_slave_destroy). Bug report at the Gentoo Bugzilla (reported and bisected by Martin von Gagern). [1] (stack trace [2]) I think that the problem is that (after commit 4e6c82b) __scsi_remove_device() is called if slave_alloc() in scsi_alloc_sdev() fails. But __scsi_remove_device() calls slave_destroy(), which (I think) doesn't make much sense (ie to call slave_destroy() when slave_alloc() fails). For sym53c8xx, this results in a NULL pointer dereference (struct sym_lcb pointer) in slave_destroy().
