output of hwinfo on the 11.4 rescue system
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.14)

I'm running an old PC (PIII 700 MHz with two Samsung pata disks attached to
a Promise Ultra133Tx2 PCI controller) under suse 10.3. Everything works as
expected. Now I try to upgrade to suse 11.4. Before doing this, I boot into
the rescue system of the 11.4 installation DVD in order to change the
partitioning. This involves copying some 20 GB of data between several ext3
file systems residing on one of the two disks. It turned out that i/o
performance during these operations was only 1/10 or worse of the
performance observed under suse 10.3. Same result with "hdparm -t", which
reports an i/o throughput of 5 MB/s under suse 11.4, but of 55MB/s under
suse 10.3.
In the suse 11.4 boot.msg file, I find the following message: 'irq 10:
nobody cared (try booting with the "irqpoll" option)', see the attached
hwinfo file. As /proc/interrupts reveals, irq 10 is associated with the pata
disks. Booting with the irqpoll option does not make the diagnostic message
disappear, "hdparm -t", however, now reports i/o throughputs ranging between
5MB/s and 55MB/s. Trying to copy data between partitions as described above
leads to a system freeze after a minute or so. From this I conclude that using
"irqpoll" is not an option here.
I tried other boot options (acpi=off, noapic, nolapic, routeirq,
assign-buses) without any success.
Reproducible: Always
Steps to Reproduce:
1. Boot into the rescue system of the suse 11.4 installation dvd.
2. hdparm -t
