Here's the log for working & non-working kernel: # uname -a Linux LS-WXL 4.2.0-0.bpo.1-kirkwood #1 Debian 4.2.6-3~bpo8+2 (2015-12-14) armv5tel GNU/Linux # mount -t debugfs none /sys/kernel/debug # cat /sys/kernel/debug/gpio GPIOs 0-31, platform/f1010100.gpio, f1010100.gpio: gpio-28 (HDD0 Power ) out hi gpio-29 (HDD1 Power ) out hi GPIOs 32-49, platform/f1010140.gpio, f1010140.gpio: gpio-34 (? ) out hi gpio-35 (? ) out hi gpio-37 (? ) out lo gpio-38 (? ) out hi gpio-40 (? ) out hi # uname -a Linux LS-WXL 3.16.0-4-kirkwood #1 Debian 3.16.7-ckt7-1 (2015-03-01) armv5tel GNU/Linux # mount -t debugfs none /sys/kernel/debug # cat /sys/kernel/debug/gpio GPIOs 0-31, platform/f1010100.gpio, f1010100.gpio: gpio-28 (HDD0 Power ) out hi gpio-29 (HDD1 Power ) out hi GPIOs 32-49, platform/f1010140.gpio, f1010140.gpio: gpio-34 (lswxl:red:hdderr0 ) out hi gpio-35 (lswxl:red:hdderr1 ) out hi gpio-37 (lswxl:red:func ) out lo gpio-38 (lswxl:amber:info ) out hi gpio-40 (lswxl:blue:power ) out hi Cheers, Roger
