sdhc and power management
I am noticing that my Thinkpad X61 will not sleep, apparently because
the sdhc driver is not recognized as having power management. The
command that should put it to sleep is:
# sysctl -w machdep.sleep_state=3
machdep.sleep_state: 0 -> 3
but immediately afterward
# sysctl machdep.sleep_state
machdep.sleep_state = 0
The logs have the following messages, the first set during boot and
the second in response to the first command above:
/netbsd: sdhc0 at pci3 dev 0 function 2: vendor 0x1180 product 0x0822 (rev.
/netbsd: sdhc0: interrupting at ioapic0 pin 18
/netbsd: sdhc0: couldn't map register
/netbsd: acpi0: entering state 3
/netbsd: Devices without power management support: sdhc0
/netbsd: acpi0: aborting suspend
Is this a known problem with sdhc? With the Thinkpad? Any suggestions
on how to debug this?
Thanks for your help.
