read(16</mnt/us/update.bin.tmp.partial>, 0x76f2d000, 8192) = -1 EISDIR (Is a directory)
I was eventually able to make the problem go away by touching:
/var/local/system/SKIP_UPDATE_CHECK
I was wondering if anyone else has had this experience or if there's another solution?
For the life of me I don't want to remove /mnt/us/update.bin.tmp.partial because that's the only thing I know of that prevents an OTA update.

Thanks for the tip! Guess that explains why airplane mode makes a much greater impact on my PW4's battery life—it doesn't bother checking for updates with wifi off.
I've recently been getting awful battery life on my PW4 when wifi is enabled. Like significantly worse compared to PW3 5.8.x/5.9.x with similar settings and usage. I thought it may have been KOReader's sleep mode but it looks like it might just be Kindle firmware.
