My Pi (model B) runs fine, headless, for several days, and then eventually stops responding to network requests on Ethernet, requiring a hard reboot. This issue looks to be similar to others reported (eg raspberrypi/firmware#268, #552), but I'm currently using the next rpi firmware, and this issue is still present.

My syslog extract (some repeated lines removed, I've denoted in brackets):

Please post a lsusb -v if you have any other USB devices attached.

Output from sudo lsusb -v follows. I have a USB 3G dongle attached directly to one USB port. Fwiw, the power supply for the Pi is rated at 2A.

drm/xe: get rid of MAX_BINDS
14d4d0a 
Mesa has been issuing a single bind operation per ioctl since xe.ko
changed to GPUVA due xe.ko bug #746. If I change Mesa to try again to
issue every single bind operation it can in the same ioctl, it hits
the MAX_BINDS assertion when running Vulkan conformance tests.

Test dEQP-VK.sparse_resources.transfer_queue.3d.rgba32i.1024_128_8
issues 960 bind operations in a single ioctl, it's the most I could
find in the conformance suite.

I don't see a reason to keep the MAX_BINDS restriction: it doesn't
seem to be preventing any specific issue. If the number is too big for
the memory allocations, then those will fail. Nothing related to
num_binds seems to be using the stack. Let's just get rid of it.

Fixes: dd08ebf ("drm/xe: Introduce a new DRM driver for Intel GPUs")
Testcase: dEQP-VK.sparse_resources.transfer_queue.3d.rgba32i.1024_128_8
