When test more than three Genesys Logic usb3 storages (VID : PID = 0x05e3 : 0x0749) on rockchip platforms with usb3 host port (e.g. rk3328/rk3399) at the same time, test commands like this: for dev in `ls /dev/sd?1 | sed -e 's,1$,,'`; do echo dd if=$dev of=/dev/null dd if=$dev of=/dev/null & sleep 1 done The test fail with the following error log: xhci-hcd xhci-hcd.9.auto: xHCI host not responding to stop endpoint command. xhci-hcd xhci-hcd.9.auto: Assuming host is dying, halting host. xhci-hcd xhci-hcd.9.auto: Host not halted after 16000 microseconds. xhci-hcd xhci-hcd.9.auto: Non-responsive xHCI host is not halting. xhci-hcd xhci-hcd.9.auto: Completing active URBs anyway. xhci-hcd xhci-hcd.9.auto: HC died; cleaning up This patch sets the max_sectors to 128 (64K) to workaround this issue, and it doesn't affect the transmission rate.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
