There are many posts in the forums about long boot times with USB drives and such attached. Your post is in my opinion a variation on that theme. It's well known that drivers are done in haste and almost always buggy or barely working.
To fix this may require a few suitcases of cash or maybe a trailer load.
You don't want to know how we fix this issue. (we change the machine.)
Why we do that is that we have PCs that run a production line and we "did the math" and found it was cheaper to swap out the slug than to spend days fussing over drivers. There are some that call us names for taking the easy path (the dark side?) but for us it's all about the time (time = money.)
Im having an irrgularly occurring problem with my FSC AMILO M1452 (mP1800, 2G Ram) and Win XP Home SP3.
I use the laptop mostly on a dektop connected via USB to a Printer (Canon MP 610), an external sound unit (Emagic 6/2), two USB Drives and a varying assortment of card readers, webcams and USB sticks. The latop is hooked up most of the time but does occasionally leave the desktop for mobile use (about once a week)
On a clean install, the system runs fine and the Sycon DPC latency checker gives readings around 150-300ms. Periodically for a year ormso now, the system suffers a driver failure which causes DPC latetncy to explode to 22000ms and cause the system to hang and judder, rendering it pretty much useless. CPU usage has frequent 100% peaks but there is no obvious culprit in the task manager.
The other syptoms appear to be these: On booting, the system hangs when detecting one of the USB drives (it appears to be consistently the 750 Gig one, but I cant gurantee that), unplugging that drive allows the system to boot, but dpc latency remains broken. re-installing or updating all the obvious driver candidates like sound, network, wlan seems to have no effect. The only thing tat saves the system is to retore to to a previously know stable install point or do a repair install of XP. After re-installing all appropriate drivers the sytsme runs smoothly again until whatever causes this faiilure re-occurs.
I suspect that the failure is caused by me being too keen on "hotplugging" the USB peripherals when I go mobile (sometimes Im in a hurry and just rip out the USB plugs) but I have no idea hwat is actually breaking.
Does anyone have an idea a) what might be breaking or b) how I coudl go about debugging the latency issues? just randomly re-installing drivers doesnt seem to get me anyhwere.
"Stop hotplugging the USB devices" would be good advice too, but id like to udnerstand whats going on so I can perhapsrepair it without re-installing or restoring XP all the time.
I Have apparently experienced failed Apple software installations around the onset of latency issues - Could one of the unwanted tools apple tries forcing on me with iTunes be at fault? I also supected my Emagic 6/2 unit whose drivers are pretty old, but removing and re-installing just those doesnt seem to heal the system.
Thx for any advice and help
