Undocked X31 oddity, might be ATA related.

Hi,

    Workaround found. Boot TP with IBM_PRELOAD OS, and disable the
"Device Bay" via "Thinkpad Configuration" utility, accessible from
Start -> Access IBM menu. Now everything is fine under
-CURRENT. Fn-keys, suspend, shutdown -[prh] are all OK now.

    Major dmesg diff after turning off "Device Bay":

-ata1: reset tp1 mask=03 ostat0=00 ostat1=00
-ata1-master: stat=0x00 err=0x00 lsb=0x00 msb=0x00
-ata1-slave:  stat=0x00 err=0x00 lsb=0x00 msb=0x00
-ata1: reset tp2 mask=03 stat0=00 stat1=00 devices=0x0
 ata1: at 0x170 irq 15 on atapci0
 ata1: [MPSAFE]

    Conclusion: so far this workaround is only required for -CURRENT.
FreeBSD 4.x and the IBM_PRELOAD OS both work happily with/without this
workaround.

Clive
