Public bug reported:
Binary package hint: linux-image
Ubuntu 8.04, i386, linux-image 2.6.24-19.36
Suspend works fine but on resume the system only shows a blank screen.
USB devices show no sign of life nor does the caps lock key show any
response.
Investigating with "echo 1 > /sys/power/pm_trace" gives the following
result in dmesg after a reboot:
[ 10.367810] hash matches
/build/buildd/linux-2.6.24/drivers/base/power/main.c:112
[ 10.367850] hash matches device ttys9
[ 10.367862] hash matches device ttypc
[ 10.367965] hash matches device PNP0100:00
A find command gave two hits in /sys:
[EMAIL PROTECTED]:~# find /sys -name "PNP0100:00"
/sys/devices/LNXSYSTM:00/device:00/PNP0A03:00/device:09/PNP0100:00
/sys/bus/acpi/devices/PNP0100:00
However "lspnp" shows nothing about a "PNP0100" device.
[EMAIL PROTECTED]:~# lspnp
00:00 PNP0a03 PCI bus
00:01 PNP0b00 AT real-time clock
00:02 PNP0c04 Math coprocessor
00:03 PNP0200 AT DMA controller
00:04 PNP0c02 Motherboard resources
00:05 INT0800 (unknown)
00:06 PNP0303 IBM enhanced keyboard (101/102-key, PS/2 mouse support)
00:07 PNP0f13 PS/2 port for PS/2-style mice
00:08 PNP0401 ECP printer port
00:09 PNP0501 16550A-compatible serial port
Therefore I am not able to deduce a module that could be the cause for
the failing resume.
I tried unloading a few modules that are not absolutely necessary but
the system never resumed.
