This is on kernel 2.6.14.2 on x86-64. The problem is fixed in 2.6.15-rc2 but I'm curious as to whether anybody knows which patch solved this, so that it can be submitted to linux-stable and added to Gentoo's kernel releases. Here is the oops (transcribed from a low quality photo, might include some typos) scsi0: LSI Logic MegaRAID driver scsi[0]: scanning scsi channel 0 [Phy 0] for non-raid devices scsi[0]: scanning scsi channel 1 [Phy 1] for non-raid devices Unable to handle kernel null pointer dereference at ..
