iop(4)/iopsp(4) hang

[SAITOH Masanobu <msaitoh%execsw.org@localhost>]

 Hi.

 Today, I fixed two bugs in iop.c and iopsp.c,
but it still hangs while booting:

> pci3 at ppb2 bus 3
> pci3: i/o space, memory space enabled, rd/line, wr/inv ok
> ppb3 at pci2 dev 0 function 2: vendor 8086 product 032a (rev. 0x09)
> ppb3: PCI Express capability version 1 <PCI-E to PCI/PCI-X Bridge>
> ppb3: disabling notification events
> pci4 at ppb3 bus 4
> pci4: i/o space, memory space enabled, rd/line, wr/inv ok
> iop0 at pci4 dev 1 function 0: allocated pic ioapic0 type level pin 18 level 6 to cpu0 slot 1 idt entry 97
> I2O adapter <ADAPTEC 2110S>

> iopsp0 at iop0 tid 8: SCSI port <ADAPTEC, AIC-7899, 00000001>
(hang)

It hangs both with and without LOCKDEBUG and I couldn't enter DDB.
I can't debug next 1 week, so I'm glad if someone debug it.

 Thanks.
