Great, thanks. That tells us all sorts of stuff about your setup.

For linux-scsi reference, Chase's /proc/slabinfo says:

scsi_cmd_cache 1547440 1547440 384 10 1 : tunables 54 27 8 :
slabdata 154744 154744 0

It can sometimes be quite large. I always say -s 1000000 to make sure
everything got there.

It's compile-time configurable with CONFIG_LOG_BUF_SHIFT and boot-time
configurable with log_buf_len=n.
