This is sort of a follow up to the issue of kernel panic when a system is booted with umass device plugged in. Cursory point: I remember having the issue myself when I loaded scsi_low and cam as modules. I blamed it on sg being present in cam.ko, but I have no facts. After I added scsi devices to kernel (sans sg) I stopped having the panics. BTW, I use RELENG_7, i386, UP. Anyway, I see a different issue with booting while a umass device is connected. First issue was that k3b hasn't found my two cd/atapicam devices. Then I executed camcontrol rescan all, it failed with EINVAL. camcontrol reset all - the same error. ktrace showed that the error came from ioctl on xpt device. I rebooted without the umass device and everything went back to normal. I'll try to do more debugging later. -- Andriy Gapon
