A friend of mine, is unable to install FreeBSD on the secondary hd
of its computer.

This is what the console says trough the installation process:

ad2s1a: hard error reading fsbn 34...
... : DMA problem fallback to PIO mode

[repeated 3 times with different values]

spec_getpages: (#ad/0x20010) I/O read failure: (error=5)
        bp 0xc34ed5bc vp 0xc7a35980

        size: 36864, resid: 36864, a_count: 36864 valid: 0x0
        nread: 0, reqpage:0, pindex: 2, pcount: 9

vm_fault: pages read error, pid 152
cp: /kernel: Bad address

the ide chipset is Ali M1543C

the hw (hd, pc, etcetc) is perfect, the same problem occurs with 4.0-S, 4.1-S,
4,2-S, etcetc 

any idea?
