Re: mdraid10 regression in 2.6.27.4 (possibly earlier)

I'd just like to note that I have the same problem with 2.6.27.
/proc/mdstat is stuck saying
      
md4 : active raid10 sde3[6](S) sdf3[4] sdd3[2] sdc3[1] sdb3[0] sda3[5]
      131837184 blocks 256K chunks 2 near-copies [6/5] [UUU_UU]
      bitmap: 31/126 pages [124KB], 512KB chunk

while the kernel complains every second or so:
