Not quite what you asked, following is with 6GB laptop HDD in USB
enclosure on /dev/sdb, main drive is Seagate SATA /dev/sda.
More hardware info on http://scatter.mine.nu/test/boxen/sempro/
includes an lspci -v, mobo, CPU, HDD info
nVidia driver not loaded, box running headless to ssh terminal.
USB optical mouse only other device plugged in
USB drive plugged in prior to reboot both times
Summary: interrupts being lost on latest? No HDD slowdown.
All USB ports use IRQ18, SATA on IRQ17
More info on request.
--Grant.
stable then latest:
2.6.11.11: after many runs, plus hardware info:
