esd failes to shmget() with EACCES
Last modified: 2008-04-17 09:09:47 EDT
Description of problem:
esd failes to initialize IPC shared memory.
This is a tail of strace esd log:
open("/dev/snd/controlC0", O_RDWR) = 5
ioctl(5, USBDEVFS_CONTROL, 0xbf833634) = 0
ioctl(5, UI_DEV_CREATE, 0xbf833610) = 0
close(5) = 0
semget(2037514327, 1, IPC_CREAT|0600) = 196608
semop(196608, 0xbf833bde, 2) = 0
shmget(323539665, 384, IPC_CREAT|0600) = -1 EACCES (Permission denied)
write(2, "ALSA lib pcm_dmix.c:851:(snd_pcm"..., 44ALSA lib
pcm_dmix.c:851:(snd_pcm_dmix_open) ) = 44
write(2, "unable to create IPC shm instanc"..., 33unable to create IPC shm
instance) = 33
write(2, "\n", 1) = 1
shmdt(0) = -1 EINVAL (Invalid argument)
unlink("/tmp/.esd/socket") = 0
rmdir("/tmp/.esd") = 0
exit_group(2) = ?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Just launch esd
Esd either finishes shortly or just sits there in semop() forever.
esd should run and do its job.
There are chances this problem is dealt with kernel (2.6.17-1.2174_FC5.i686)
and/or architecture (the CPU is Pentium III (Coppermine))
as some other applications (namely firefox) come accross the same problem
Looks like a problem setting up the shared memory to use ALSA's dmix.
Reassigning to alsa-lib.

To my regret I cannot upgrade to a later Fedora release
as since Fedora 7 PATA disks are always treated as SCSI disks
and SCSI disks cannot contain more than 15 partitions,
while I do have more than twenty of them.
It seems I should have to switch to some other Linux distribution.
Well, we're not going to fix any bug in FC5. Closing.
