Bug#494471: kernel-2.6.25 unable to resync (new) md array's



Package: linux-image
Version: 2.6.25-2-686

I tried to create several software raid(md) array's on my Lenny system, but unfortunately the resync/recovery of the array's hangs like this:

md3 : active raid1 sdb6[2](F) sda6[0]
      126953536 blocks [2/1] [U_]
[>....................] recovery = 0.0% (103296/126953536) finish=634251.2min speed=0K/sec

md4 : active raid6 sdf1[3] sde1[2] sdd1[1] sdc1[0]
      976767872 blocks level 6, 64k chunk, algorithm 2 [4/4] [UUUU]
[>....................] resync = 0.2% (1037056/488383936) finish=289250.7min speed=0K/sec

I also tried a 2.6.25.14 vanilla kernel, which I built myself but this one suffers from the same problem. Downgrading to Lenny's 2.6.24 kernel, however, fixes the problem! I guess it should (could?) be fixed upstream. But at least we want this fixed before the final release of Lenny, right?

I don't know if it is related to the type of hardware I'm using, here are the relevant details of my setup:
- Pentium III 500E
- 2x Promise TX4 SATA controller
- 4x Seagate 500Gb SATA disk
- 2x Samsung 640Gb SATA disk
