Subject: Re: [Bug report] System lockups on Tyan S2469 and lots of io [smp boot time problems too :(]

Ok, so I forgot the vmstat output too :/
Looks pretty similar to the vmstat output with the hang of 2.4.21.

Using 2.4.19 it takes longer to take the system down, there is a long
time where data actually gets to the array, before the behaviour where
only a few blocks get written out anymore, untill the system hangs.

The date on the file the vmstat was written to is Jul  7 17:52,
every second it was written (last possible one at 17:52:59, when the
system hung)... That makes the 'important point in time' about 17:52:59 -
29, which is 17:52:30. The closest trace I have is from 17:52:44

The cp process is then already in state D (uninterruptible sleep), it
wasn't in state D in the trace at time [17:50:39], when it was on the
run queue.

Can anyone make sense out of this ? :))

best regards,

Vincent
