[2.6.6 panic] via-rhine and acpi sleep 3

[2.6.6 panic] via-rhine and acpi sleep 3

[Benoit Dejean]

hello, i'm getting troubles with my epia boxes : epia via motherboard + 
C3 processor.

the acpi STR sleep works fine (the CPU fan goes down) and wake up is ok. 
But, i'm experiencing bugs with the builtin via-rhine network card. on 
wake up, the network card seems to have been not correctly suspended : 
it doesn't work anymore. i tried to find a way with acpi so that the 
network interface is downed before sleep, the module unloaded and vice 
versa on wake up. but that doesn't work.

on wake up, trying to re-activate my netcard, i often get some message 
obout ill-formed ethernet frames. i also often get kernel panic but i've 
not been able to save the kernel panic trace. i don't know how, so if 
somebody could tell me how to save it ...

regards,
Benoit

i'm afraid it's empty, nothin about the panic is saved there. i've tried 
to run a while:; do sync; done and to ajust  kernel log buffer size from 
  14 to 10 but i've not been able to retrieve anything

Try suspend-to-disk working, first.

i'm working with set top box without disk, so i'm not interesting in 
STSW. i've been able to save some logs by mounting /var/log with NFS, 
but i've handwritten the kernel panic message.

so i've tried STSW, but it first failed because i have no swap partitions

after adding a swap file, i've tried again
saving did well, but when trying to wake up my box rebooted it. nothing 
in the log.

i'm very willing to make tests but my boss he's not :/ so i have no time 
to spend on testing Suspend To Disk.

thank you
