Ok, I had to increase that to 45 seconds to get it working automatically. Leaving notes here for people with the same problem, needing a workaround until this gets fixed. More precisely, here is the boot log with that I get with rootdelay=15 only: [ 5.720053] floppy0: no floppy controllers found [ 5.729329] work still pending Here it pauses for about 10 seconds more, i.e. up to the rootdelay, then this: Begin: Loading essential drivers ... done.

Warning: starting local-top mdadm Warning: MD_DEVS is all Begin: Assembling all MD arrays ... mdadm: No devices listed in conf file were found. Failure: failed to assemble all arrays. done. I.e. it failed to assemble. Then it pauses again for about 15 more seconds. [ 32.775174] scsi0 : ioc0: LSISAS1068E B3, FwRev=00192f00h, Ports=1, MaxQ=266, IRQ=16 At last scsi responds...
