swsusp problem

[curious]

hello.
i write because swsuspend don't work for me.
i try to echo disk > /sys/power/state
and just nothing happens, i have blinking cursor and machine freezes.

when i enabled debug i got :
stopping tasks: ========|
Shrinking memory... done (2684 pages freed)
swsusp: Need to copy 1454 pages
swsusp: critical section/: done (1454 pages copied)

.... and machine just sits there , doing nothing.
after reboot it boots like usual.

machine is Ts30M Viglen Dossier 486 SM
kernel is 2.6.18-rc5
here is config : http://zjeby.dyndns.org:8242/viglen.config

Could you boot the kernel with the init=/bin/bash command line argument
and do the following:

# mount /proc
# mount /sys
# echo 8 > /proc/sys/kernel/printk
# swapon -a
# echo disk > /sys/power/state

and see what happens?

intel 486 cpu?

Can you try with minimal config?

What kind of machine is that? What cpu? Really 486?

yes, excuse me (fixed)

> intel 486 cpu?
uhm. yes.
i see cpudetection fail... but as i checked just on
this 486 and pentium 133 - on both 'cache_size' field
in cpuinfo shows 0k .

on pentium2 machines (pentium II deschutes) cache is detected ok .

yes, it's viglen dossier 486 based laptop .
cpuinfo detects it as 'GenuineIntel'
cpu family : 4
model : 3
model name : 486 DX/2

Forget it, this thing does not support 4MB pages, and swsusp currently
needs them. (We'll need to fix that, but not now -- fix is port of
page-table handling code from x86-64).

It should die with

        if (!cpu_has_pse) {
                printk(KERN_ERR "PSE is required for swsusp.\n");
                return -EPERM;
        }

...can you investigate why it does not?

Oops, aha, really? I thought only pentium+ supported 4MB tables?

Does it also support cr4? Anyway, someone interested in history needs
to play with this one ;-).

thinkpad 360Cs keyboard problem

[Piotr Gluszenia Slawinski]

well, certainly 2.6.18 issue...
kernel boots up fine, but keyboard is totally messed up,
and locks up after some tries of use.

on 2.4.20 kernel keyboard works just fine

Are you saying that it works on 2.6.17 and is broken on 2.6.18?

Could you try describing the exact issues with the keyboard? Missing
keypresses, wrong keys reported, etc?

Thanks.

no, it works on 2.4.20. i didn't tried yet with other 2.6.x versions.

btw. now i compiled 2.4.33.3 using gcc 3.4.6 ,
and even though i used 486 in cpu type resulting binary requires
TSC+ from cpu :o (now recompiling with gcc-2.95.3 , and
config_notsc and it seems to boot up)

however weird behaviour aswell, because stops just after init...
no matter wheter i use init=/bin/bash or regular init.
it reports mounting root fs (ext2), then freeing unused kernel
mem (52k) and stops .

when i press keys i see output like it should be , so at least
keyboard work :)

with 2.6.18-rc5 it boots just fine, but ofcourse keyboard is
broken.

with prink enabled it prints series of 'unknown scancode'
and keys are randomly messed up, and it changes, so like pressing b
results with n, then space, then nothing at all.
after some tries keyboard locks up completely.

so wrong keys reported

Are you loading a custom keymap by any chance? Could I please see
dmesg with "i8042.debug log_buf_len=131072"?

no custom keymaps . init=/bin/bash :d
uhm, i don't get what you mean by this dmesg syntax :o
i should probably attach serial conole and send you whole output,
as now (as keyboard is unuseable) i can't scroll screen.

btw. serio: i8042 KBD port at 0x60,0x64 irq 1
is found.
also
input: AT Raw Set 2 keyboard as /class/input/input1
is reported

ah, i use gcc-4.1.1 to compile kernel .


-------------------- stuff below might be result of my ignorance

i just checked 2.2.27 kernel. it behaves quite identical to 2.4.33.3,
just after 'freeing unused kernel memory' it touches disk , and just
sits there. kepresses are echoed, and keyboard output is 
ok. i can reboot it by ctrl-alt-delete too .
when i boot it with 'fosh' shell commandline appears, but trying
to use any tool like bash, ls , etc results with signal 11.
tools are statically compiled against glibc-2.4 (compiled for 486 cpu
on gentoo)
busybox works fine.

on 2.4.33.3 kernel Xvesa (from kdrive package) complains
'set_thread_area failed when setting up thread-local storage'

cardmgr works fine aswell...(though was linked against different glibc)
  i guess there is some problem with math emulation and glibc,
as on 2.6.18 everything works just fine.

i recall few years ago i tried to make 386SX work on 2.4.20 , and 
there were problems with math emulation (some apps worked, some not)

These were kernel boot options. If you let the system boot normally
so that syslog is running I'd expect debug messages end somewhere
(like in /var/log/messages) so you could reboot and send me that file.

It could be that it lies about being in raw mode and actually is in
translated mode.
