Thanks for the responces and suggestions. I appologise for the html formated message.
I'll see if this one comes out as plain text...
I've tried passing ide=nodma to the kernel. This caused problems, see below, with
formatting and with bonnie++. Errors were :
"hdg: status error: status=0x58 { DriveReady SeekComplete DataRequest }"
Yet I've used this setup without DMA and it worked fine (slowly). When I first
installed the ATA-100 card and drives I did not have the driver compiled and kernel
defaulted to using the generic IDE driver with PIO. I'm currently rebuilding the
kernel with JFS but without the PDC202xx driver to see what happens.
I'm using bonnie++ 1.02a.
I ran it with a variety of command line aroguments as listed below. On /dev/md3 it
bonnie++ hung with "-n 10:0:0", "-n 8:4096:4096" and "-n 4:16384:16384" which seems to
indicate the problem is related not to the number of files but to their aggregate
size.
Could this be a problme with the PDC202xx driver that is only aggravated by JFS? I
hope running without the PDC202xx driver will tell.
Thanks,

What follows is a listing of invocations of bonnie++. If there is no comment on the
next line then the test succeeded. Otherwise I note what bonnie++ had last displayed
before hanging.

As far as I can tell, with the driver for the PDC202xx chips in the kernel, PIO to
the PDC20268 doesn't seem to work.
reboot... with DMA again

I believe I ran out of inodes. Bonnie didn't hang but exited normally.

Again too few inodes.
I give up, I can't seem to duplicate the problem with the partition formated
as ext3.
