Description Enrico Manzini 2004-03-17 02:24:33 UTC 
Distribution: Gentoo

Hardware Environment: Fujutsu Siemens Amilo M6800 (PIV 1700). Output of `lspci
-v` is in attachment.

Software Environment: Output of `lsmod` is in attachment. The kernel is loaded
with the following parameters: 
root=/dev/hda5 vga=791 acpi_sleep=s3_mode

Problem Description: after suspending to ram and succesfully getting the system
up, general failures happen. The HD activity LED is stays fixed on, and the
system hangs when I do anything. I could experience various behaviours:
sometimes I get a kernel Oops, once the system beginned a shutdown with the
command `lsmod` (?!), more often the systems just hangs with the first command I
give.

Steps to reproduce: send the system in suspend-to-ram with `echo -n "mem" >
/sys/power/state` (but things are the same with `echo 3 > /proc/acpi/sleep`).
The system goes in suspend mode. Pressing the power button wakes up the system
within a few seconds, but when I try anything, bad stuff happen.

I had the same results with both kernel 2.6.1 and 2.6.3-r1

same with 2.6.9?
Comment 4 Len Brown 2005-01-03 20:14:33 UTC 
please re-open if this issue exists in 2.6.10 or later.
Comment 5 Enrico Manzini 2005-01-16 07:05:42 UTC 
sorry for the long delay, I had my laptop down for repairs for a couple of months

now that I have it back working, I've tested a 2.6.10-r4 kernel from gentoo. the
problem now is that system goes in suspend mode, but when I resume, after asking
for BIOS passwd, reboots instead of resuming.
Comment 6 Enrico Manzini 2005-01-18 02:45:24 UTC 
Some other news. I've tried also a gentoo-dev 2.6.10-r5 kernel (which is in "~"
mode, which should mean "unstable"). 

here the effect is different again, I can suspend but after resume, just after
typing the BIOS passwd, I get a yellow "Linu" writing, and the system hags badly
(no response, I have to hard reboot).

Hiro's patch

Great to know you can see 'Linu' on the screen.
Could you please try attached patch? It's from Hiroshi Itoh <hiroit AT
mcn.ne.jp>
Comment 8 Enrico Manzini 2005-01-19 04:14:53 UTC 
tried the patch (note: one hunk did not succed, I had to add one line manually,
but I think it's not a problem)

the system now wakes up, and immediately reboots :P
Comment 9 Shaohua 2005-08-18 00:10:35 UTC 
We find several similar issues in VIA chipset based system, unknown the 
reason :(.
