Subject: [2.6.27-rc6-mm1] Boot hangs while initializing SCSI disk.

Hello.

Boot process seems to fallen into infinite loop, as CPU usage became 100%
after printing below messages.
Comparing two outputs, it hangs just before printing
"sd 2:0:0:0: [sda] 8388608 512-byte hardware sectors (4295 MB)" line.

Config is at http://I-love.SAKURA.ne.jp/tmp/config-2.6.27-rc6-mm1

Regards.
