is there a linux running on jvm arch ?
I 've tested the User Mode Linux a few times ago, and it gave me an idea: given the fact that we had a GCC which produce bytecode from C, it would be possible to produce a port of linux(a new directory "jvm" in the arch dir) which would run in a Java Virtual Machine. (after some inquiries such compiler does not exist :-( ) I'm dreaming of a linux booting in a browser applet(imagine sending such thing in a mail to MS peoples ) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
[BUG]2.4.0test11 and 2.4.0test12-pre3, sound looping for ever
Hi,
i've got a strange bug: after some hours of uptime sound starts looping
for ever. I always have this in my
logs: "unexpected IRQ trap at vector 7d". There's no Ooops and i can
only stop sound by killing "esd". Of
course, i can't run it anymore after it has been killed.
2.4.0test10 wasn't exibiting this.
my soundcard uses es1371 module. the box is a BP6 + 2celerons. This bug
is hard to reproduce, it
is really odd and happens randomly.(if it happens again i'll try to
check /proc/interrupt)

I got the same problem for an old 486 with no PCI, as yenta_socket doesn't work, i have to add CONFIG_I82365 in order to have things work. 'till this is set and recompiled, everything works perfectly. The controller is a VLSI 82C146. I'm problably missing something, but these's two things i don't understand: -why PCMCIA depends on PCI at compilation time -why yenta is activated for i82365, as it doesn't do the job i82365 did. -- %-% % FORT David, % % 7 avenue de la morvandière 0240726275 % % 44470 Thouare, France[EMAIL PROTECTED] % % ICU:78064991 AIM: enlighted popo [EMAIL PROTECTED] % %--LINUX-HTTPD-PIOGENE% % -datamining <-/| .~. % % -networking/flashed PHP3 coming soon | /V\L I N U X% % -opensource| // \\ >Fear the Penguin< % % -GNOME/enlightenment/GIMP | /( )\ % % feel enlighted| ^^-^^% % http://ibonneace.dnsalias.org/ when connected % %-% - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

2.4.0test10 not booting on 486 laptop
When 2.4.0test10 bootup, i got the "Loading" message, then "Uncompressing kernel...", i can see quickly "Booting.", and it does it: it reboots. My last kernel was 2.4.0test7, and was not exibiting the problem. I've recheck my .config, but it's the same as for 2.4.0test7. My gcc: [root@Djinn linux]# gcc -v Reading specs from /usr/lib/gcc-lib/i586-mandrake-linux/2.95.2/specs gcc version 2.95.2 19991024 (release) [root@Djinn linux]# according to Changes may be good. The laptop is a 486dx2@40 compaq contura 400cx, two thing that may be important: it has early cpuid support(many changes occured in this area recently), and it doesn't have any PCI bus(but kernel is compiled with it, in order to have Card drivers). -- %-----% % FORT David, % % 7 avenue de la morvandière 0240726275 % % 44470 Thouare, France[EMAIL PROTECTED] % % ICU:78064991 AIM: enlighted popo [EMAIL PROTECTED] % %--LINUX-HTTPD-PIOGENE% % -datamining <-/| .~. % % -networking/flashed PHP3 coming soon | /V\L I N U X% % -opensource| // \\ >Fear the Penguin< % % -GNOME/enlightenment/GIMP | /( )\ % % feel enlighted| ^^-^^% % http://ibonneace.dnsalias.org/ when connected % %-% - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

I think nobody would complain if "being fun to hack on(TM)" could also be "Fast developped(TM)". Anyway the developpement of the kernel is already modular, as teams are working quite independantly, and send theirs diff when a release is about to come.

fixing dual head issue with DRI
Hi, i've made this little patch against drivers/char/drm/proc.c to
enable dual head in /proc/dri. I'm quite sure
that it's not SMP safe, so if anybody could give a look. Anyway it
worked for me.

[2.4.0test10-pre3]drm_proc_init incorrect when multiple device are registering
Hi, I've just got a look at file drivers/char/drm/proc.c, correct me if i'm wrong but when registering using "drm_proc_init" each device supporting drm duplicates the dri dir entry, as "create_proc_entry " blindly create a new dri entry even if one already exists. IIRC a few month ago the same kind of error was occuring in /proc/irq, perhaps we should check in create_proc_entry that an entry exists before creating it, this could prevent each driver from doing this job. -- %--IRIN->-Institut-de-Recherche-en-Informatique-de-Nantes-% % FORT David, % % 7 avenue de la morvandière 0240726275 % % 44470 Thouare, France [EMAIL PROTECTED] % % ICU:78064991 AIM: enlighted popo [EMAIL PROTECTED] % %--LINUX-HTTPD-PIOGENE% % -datamining <-/ | .~. % % -networking/flashed PHP3 coming soon | /V\ L I N U X % % -opensource | // \\ >Fear the Penguin< % % -GNOME/enlightenment/GIMP | /( )\ % % feel enlighted | ^^-^^ % % http://ibonneace.dnsalias.org/ when connected % %-%
[DRI]2.4.0test10-pre3: duplicate /proc/dri with two DRI cards
Hi, i've just borrowed an ATI Rage Fury(AGP) which support DRI, i also have an older Matrox Mystique which also support DRI. When starting an X server using both cards, i can see TWO /proc/dri directories. In the /proc/dri directory there's a 0 subdir, i think in normal situation i should have a 0 and a 1 directory instead of two dri ones. -- %--IRIN->-Institut-de-Recherche-en-Informatique-de-Nantes-% % FORT David, % % 7 avenue de la morvandière 0240726275 % % 44470 Thouare, France [EMAIL PROTECTED] % % ICU:78064991 AIM: enlighted popo [EMAIL PROTECTED] % %--LINUX-HTTPD-PIOGENE% % -datamining <-/ | .~. % % -networking/flashed PHP3 coming soon | /V\ L I N U X % % -opensource | // \\ >Fear the Penguin< % % -GNOME/enlightenment/GIMP | /( )\ % % feel enlighted | ^^-^^ % % http://ibonneace.dnsalias.org/ when connected % %-%

USB still have problems, when starting to grab with my ov511 webcam i got
the attached oops. This bug appeared
in test9-preX(X beeing at least > 2) series. Some people have
claimed that test10-pre1 fixed the problem, but
the bug is still present in the last two pre(test10-pre1 and test10-pre2).
To be noted:
-this oops is obtained with "Enforce USB bandwidth allocation", but
it occurs in the same place when disabled
-I'm using usb-uhci
-the attached oops is truncated as each following schedule call produce
a new oops

The failed "Read Table of Contents" packet command was:

Please note the "Disk change detected": i haven't touch the drive between
the two hdparm.
When i attempt to mount the drive, the whole system got stuck with nothing
in logs(even on serial console).
I've tried different configurations(multimode on/off, reset ide2 on start, etc..)
the result is always the same: lockup when mounting and garbage in logs
when hdparm.
Feel free to ask for more tests or for my whole .config.

Are you getting both the username and password prompts
and then getting nothing after entering the password?
This is a behavior I am seeing on a laptop Pentium II.
In my case, I can CTRL-ALT-F[1-6] to get to another
VT. All attempts to log in any VT display meet the same
fate. Also, attempting to log in using GDM fail in
this way. In my case, the UI GDM continues to respond.
Lastly, trying to CTRL-ALT-DEL to initiate a shutdown
does cause the TERM and KILL signals to be sent to
all processes. Then the shutdown process locks up
after a message is printed about unloading the
keyboard driver.
Interestingly, if I boot in single mode ("linux single"
at the boot prompt), and then load GDM, I am able to
log on with no trouble.
I have sent a message to the maintainer of the
shadow-utils package, but have gotten no response.
I suspect this problem has to do with a fsck-up on
my part in getting util-linux configured properly when
I built it. I rebuilt util-linux with the sources
pointed to by Changes several development kernel
revisions ago (~2.4.0-test7).
