[Bug 254890] [NEW] Resume failure on Acer TravelMate 662

[Peter Klotz]

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:

root at centrino:~# 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.

root at centrino:~# 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.
