I'm aware you have a workaround, (use another unit), but I'll address the
problem further:

I'm quite familiar with that part of the SDHCI implementation in the
firmware.  My gut feel is that this XO-1.5 has a damaged wireless
card.  Please provide the serial number of the XO-1.5 for further
analysis, thanks.  (None of the issue data contained this).

Please also do a long run test of using the wireless card in Linux, such
as associating with an access point and then pinging for a few hours.
Check the kernel logs (dmesg) for interesting output.
