Bug Description
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/
[ 10.367810] hash matches /build/
[ 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@centrino:~# find /sys -name "PNP0100:00"
/sys/devices/
/sys/bus/
However "lspnp" shows nothing about a "PNP0100" device.
root@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.

importance: | Undecided → Medium |
status: | Incomplete → Triaged |
Detailed investigation using kernel.org kernels:
2.6.24.7: hangs on resume (like Ubuntu 2.6.24-19.36)
2.6.25.15: works (with appropriate HAL quirks)
2.6.26.2: hangs on suspend
Ubuntu 8.10 Alpha (Kernel 2.6.26) also hangs on suspend.
