Hi, I got some oops with test8; the first time I got it it was under test8-wli1; but it seems the same is happening under plain -test8. This is the original bug report:

The system was working well. Then I decided to run totem - a neat video player. It hanged. Trying to kill it I did "ps xa"; suprisingly after pid 560 ps (and the terminal) stopped and hanged. The rest of the apps (xchat, Xfree) were still alive. Then I fired another terminal, did /proc/562 (the following pid after 560); I run ls; and ls hanged. I fired another terminal, and I did 'find /proc'; and I got the oops. Some seconds after that the system locked up completely. Box is a dual p3; 256 MB ram, ide disks, running debian sid, no NPTL. Config pasted below.

Hi, I got some oops with test8; the first time I got it it was under test8-wli1; but it seems the same is happening under plain -test8. This is the original bug report:

Might be best to post the oops from mainline. I've made substantial /proc/ changes, so they may not be related.

Might be best to post the oops from mainline. I've made substantial /proc/ changes, so they may not be related.

Sure, I'm sorry. Still I haven't got an oops under test8 but the symptoms are the same:

o esd is running.
o Run totem. The first time it doesn't hang.
o run totem again. It'll stop in
open("/dev/dsp", O_WRONLY|O_NONBLOCK|O_LARGEFILE
So, it seems that esd is blocking the access to /dev/dsp; so I've to kill it (very common when you use esd)

o but killall esd hangs too:

open("/proc/570/stat", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x401d8000 read(3, "570 (gconfd-2) S 1 530 482 1025 "..., 1024) = 192
close(3) = 0
munmap(0x401d8000, 4096) = 0
open("/proc/572/stat", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x401d8000 read(3,
and it hangs here

o If you run ps ax, i'll hang too:
stat64("/proc/572", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
open("/proc/572/stat", O_RDONLY) = 6
read(6,

o If you're running gnome; it'll hang because it wants to make noise and it's waiting for /dev/dsp to be freed

I wasn't able to get an oops; the one which happened in -wli1 may be unrelated as wli said; but I'll continue trying to reproduce it.

Hi, I got some oops with test8; the first time I got it it was under test8-wli1; but it seems the same is happening under plain -test8. This is the original bug report:
The system was working well. Then I decided to run totem - a neat video player. It hanged. Trying to kill it I did "ps xa"; suprisingly after pid 560 ps (and the terminal) stopped and hanged. The rest of

were still alive. Then I fired another terminal, did /proc/562 (the

Quoted 4 lines

following pid after 560); I run ls; and ls hanged. I fired another terminal, and I did 'find /proc'; and I got the oops. Some seconds after that the system locked up completely. Box is a dual p3; 256 MB ram, ide disks, running debian sid, no NPTL. Config pasted below.

Two stupid bugs in my case. With a bit of noise surrounding things (e.g. EXPORT_SYMBOL() crud, init_task paranoia garbage, ->f_pos in unsigned long removal), un-reversing the arguments to find_pid() and not blowing away the last-seen tid while formatting it and later trying to use it as ->f_pos are the needed fixes.

Two stupid bugs in my case. With a bit of noise surrounding things (e.g. EXPORT_SYMBOL() crud, init_task paranoia garbage, ->f_pos in unsigned long removal), un-reversing the arguments to find_pid() and not blowing away the last-seen tid while formatting it and later trying to use it as ->f_pos are the needed fixes.

This fixes the oops in wli1, thanks; now it reproduces the same behaviour of vanilla -test8

You say the behavior of vanilla 2.6.0-test8 was the machine and/or process getting hung? And this is still happening even after the fixes?

Thing is, it's working perfectly here, though I don't have a decent way to use totem. Could you send the results of sysrq t when it "hangs"?

Yes.

Ok, I'll paste totem, esd, ps and xmms. xmms also hangs like totem; both of them are trying to play through esd (which is blocked, too). This is -test8-wli1 + fix.

You say the behavior of vanilla 2.6.0-test8 was the machine and/or process getting hung? And this is still happening even after the fixes?

Quoted 1 line · Diego Calleja Garc?a

Yes.

Thing is, it's working perfectly here, though I don't have a decent way to use totem. Could you send the results of sysrq t when it "hangs"?

Quoted 3 lines · Diego Calleja Garc?a

Ok, I'll paste totem, esd, ps and xmms. xmms also hangs like totem; both of them are trying to play through esd (which is blocked, too). This is -test8-wli1 + fix.

I suspect a deadlock on pcm->open_mutex; I'm doing some more reading around there to figure out what on earth is going on.
