Having undergone painful data loss experience originated from the
combination of said resets and a
"hey-lets-trust-the-GUI-for-moving-files-around-it-cant-be-that-bad",
I got motivated enough to toy around and see if I could figure how to
reproduce the USB device resets I've been noticing.
usb 5-2: reset high speed USB device using ehci_hcd and address 3
ehci_hcd 0000:00:10.4: port 2 high speed
ehci_hcd 0000:00:10.4: GetStatus port 2 status 001005 POWER sig=se0 PE CONNECT
ehci_hcd 0000:00:10.4: port 2 high speed
ehci_hcd 0000:00:10.4: GetStatus port 2 status 001005 POWER sig=se0 PE CONNECT
How make the usb device start resetting?
1.Start the cp of big files in one terminal from the USB drive to an
internal hard disk.
2. Go to another terminal, start vmstat 1 keeping eyes on bi/bo
3. Hold down the shift key, do not release
4. After a short bit... blam.
Now, I can't be absolutely sure its because of the keypress,
interrupts dancing around, or a late halloween trick, but if the box
is sort of idle you don't get the resets, while if it's keypressed you
do in a very short amount of time.
I tried booting with noacpi noapic, didn't have any effect.
Also, more evil events:
