imx_usb cause kworker to consume 100% of a core. #29

Closed johnstile closed 8 years ago

johnstile commented 8 years ago

Each time I run imx_usb kworker consumes 100% CPU of one core and never frees, though imx_usb exits. I can consume all cores by rerunning imx_usb

Am I doing something wrong?

Very strange. Does a simple invocation do that as well? ./imx_usb u-boot-mfg.imx

I do not see a /dev/sdb created, but one is mentioned in dmesg output. I do not understand what this means, but it does not look like a bug with imx_usb_loader.

johnstile commented 8 years ago

I figured out the problem. imx_usb correctly uploaded and booted the system over Serial Download Protocol. As the Linux kernel initialized the OTG port for Update Transport Protocol, but my Linux workstation workstation used the USB attached SCSI module (uas.ko) and /dev/sd* was not created and kworker went crazy. Another Linux workstation did not have this problem, as it used the sd driver. So a kernel configuration solved it.
