This setting has 3 enable bits in. It would be interested to determine which bit causes the lockup. Can you (anyone who sees the lockup) try:

Code:

dwc_otg.fiq_fsm_enable=1

Code:

dwc_otg.fiq_fsm_enable=2

Code:

dwc_otg.fiq_fsm_enable=4

Hopefully just one of those will lock up.

Copied two ~4GB .mkv-files from PC to USB-HDD connected to my RPi.

Average speed 3MB/sec (over wired nic)

Nothing in cmdline.txt other than boot=LABEL=SYSTEM disk=LABEL=STORAGE ssh quiet Lockup after 14-20 minutes of copying. I could still use ssh but it was sloooow, bcmstat showed over 9,000 IRQ/s


boot=LABEL=SYSTEM disk=LABEL=STORAGE dwc_otg.fiq_fsm_enable=x ssh quiet
x=0 No lockups
x=1 Lockup
x=2 Lockup
x=4 Lockup
