Comment 37 for bug 211572

This problem also affects my Toshiba Tecra M3. Suspend/resume worked under Gutsy but fails with all release Hardy kernels and the current Intrepid kernel. They would resume to a blank screen without accepting any input necessitating a hard reboot.

Adding this to /etc/pm/config.d/config:

SUSPEND_MODULES="ehci_hcd"

fixes the problem. LSPCI output is attached. /proc/version_signature is "Ubuntu 2.6.27-7.16-generic"

I found this out using the pm_trace function, the relevant portion of dmesg output is:

[ 1.851860] Magic number: 0:250:259
[ 1.851865] hash matches /build/buildd/linux-2.6.27/drivers/base/power/main.c:350
[ 1.851884] tty ttyx1: hash matches

[ 1.852017] rtc_cmos 00:08: setting system clock to 2068-04-03 03:15:29 UTC (3100648529)

I presume this bug is the correct place to file the issue, if anyone wants to report under Intrepid please do so :).
