2.6.17-1.2139_F: suspend ( sleep ) broken ?

[Charles-Edouard Ruault]

Hi All,
i've just upgraded to the latest kernel this morning. I closed the lid 
of my Alu Powerbook G4, as usual but when i opened it to wake up the 
machine , nothing happened.
I had to hard reboot.
I reproduced this 2 times today and also experience a machine freeze 
while unplugging an usb mouse & the power cord.
Has someone else experienced problems like this ?
In the meantime i went back to 2.6.16-1.2133_F, and everything is back 
to normal.
My config is
processor       : 0
cpu             : 7447/7457, altivec supported
clock           : 612.000000MHz
revision        : 0.1 (pvr 8002 0101)
bogomips        : 36.73
timebase        : 18432000
machine         : PowerBook5,2
motherboard     : PowerBook5,2 MacRISC3 Power Macintosh
detected as     : 287 (PowerBook G4 15")
pmac flags      : 0000001b
L2 cache        : 512K unified
pmac-generation : NewWorld

Running Fedora Core 5 with the latest updates.

Try unloading as many drivers as possible (starting with hci_usb and
then the USB host drivers) before you suspend. See if you can persuade
it to work, and find which the offending driver is.

Hi David,
sorry for the blackout period. I've upgraded to the latest and greatest 
this morning ( 2.6.17-1.2145_FC5 ) and noticed that the problem is still 
there.
However, the symptoms have changed a bit : When i close the lid, the 
machine goes to sleep ( bliking led etc ...), but when i open the lid, i 
hear the hard drive coming back to life and nothing more, the screen 
stays black and my only solution is to do a hard reboot.
I've tried unloading as many modules as possible and i came down to this 
shortlist, with no success :

Module                  Size  Used by
sungem                 36452  0
sungem_phy             10528  1 sungem
radeon                127240  1
drm                    84280  2 radeon
snd_powermac           52524  5
snd_pcm               102980  3 snd_powermac
snd_timer              30212  3 snd_pcm
snd                    73076  9 snd_powermac,snd_pcm,snd_timer
soundcore              11652  1 snd
snd_page_alloc         11944  1 snd_pcm
therm_adt746x          13804  0
ipv6                  296488  14
autofs4                27108  0
sunrpc                194280  1
ip_conntrack_netbios_ns     3072  0

xt_state                2240  2
ip_conntrack           64008  2 ip_conntrack_netbios_ns,xt_state
nfnetlink               8312  1 ip_conntrack
xt_tcpudp               3328  4
iptable_filter          3200  1
ip_tables              14984  1 iptable_filter
x_tables               17220  4 ipt_REJECT,xt_state,xt_tcpudp,ip_tables
ext3                  156808  6
jbd                    77236  1 ext3

looking at the logs here's what i get:
Jul  6 11:04:33 kaluha pmud[2093]: lid closed: request sleep
Jul  6 11:04:33 kaluha pmud[2093]: running /etc/power/pwrctl sleep battery
Jul  6 11:04:33 kaluha pwrctl: calling /etc/power/pwrctl-local sleep battery
Jul  6 11:04:33 kaluha pwrctl-local: sleep battery
Jul  6 11:04:33 kaluha pmud[2093]: going to sleep
Jul  6 11:08:16 kaluha syslogd 1.4.1: restart.

The last message is from the reboot, there's no sign of things happening 
when i open the lid, aside from the noise made by the hard drive coming 
back to life.
Is there anything else i can do to help pinpoint the problem ?
Thanks for your help.
PS: 2.6.16-1.2133_FC5 still works like a charm .....
