           Summary: 4.9.-rc4 produces hundreds of unusable scsi devices.

Debian's kernel log file. Note that this contains functional boots with older kernels as well earlier in the file.

With both my hand compiled 4.9-rc4 from kernel.org sources and Ubuntu's 4.9.0-040900rc4-generic the kernel creates hundred of useless /dev/sd?? devices. This system is fine with various 4.4, and 4.8 kernels.

The logs are spammed with messages like these

Storcli output from system.

Note that this occurs with really old firmware and the current megaraid firmware. The megaraid configuration is 12 one drive RAID zero arrays.

The only difference compared to 4.8/4/4 is the boot drive on the SATA controller ended up sdk instead of sdm (the last drive). It's not an issue for me as I mount things by UUID
