RE: RAID5 (along with RAID1) locks up

I see your RAID1 (md0) using sda1, sdb1 and sdc1.
Which disks/partitions is your RAID5 using?

Subject: RAID5 (along with RAID1) locks up

Hello everyone,

I'm having a somewhat large problem with using software RAID, which
occurred in multiple 2.6 kernels I tried (2.6.3, 2.6.4, 2.6.5). I have
three identical disks in the box (all SATA) and have a RAID1 (3 disks)
as root file system, which works flawlessly and I'm trying to set up a
RAID5 over all three disks for some data. When the array is initialized
(during creating or during boot), the machine locks up within 30-60
seconds. no SysRq key combinations work, and NMI watchdog interrupts
are created any more.

Is this a known problem, or am I messing something up? As I'm not sure
that this is solely a RAID problem, I have sent it to linux-kernel as
well.

As I'm only subscribed to linux-raid, I'd be great if all responses to
go there ;)

Thanks in advance for your time,
Victor
