problems with gcc 3.2.2 update

problems with gcc 3.2.2 update

[Paul Davis]

i backpedaled to 2.4.20 (vanilla, no patches). i grabbed this
morning's ALSA CVS. i used the simplest kernel config i could come up
with for my system. i recompiled everything, reinstalled, rebooted
(several times, in fact).

the system runs fine for kernel compiles, X, browsing, emacs,
development work ... in short, absolutely everything until 
an audio device is accessed. when that happens (actually, when it is
first written to), we get either an oops or the system just locks
totally solid (no magic-sysrq, nothing).

from the oops files, there are some suggestions that the issue is SMP
related. i am now downloading gcc 2.95.3 to try all over again.

Hi,

I'm writing an Audio driver (vortex) and when the DMA engine of the
cards starts transferring data everything locks up.
I'm using a simple linear DMA buffer, and i actually get
playback but for only one period. If i disable the
interrupt "period elapsed" calls the playback keeps playing the buffer
in a loop, if not it stops after one buffer pass.
If i simple disable the "trigger" call, so anything else is done but the DMA
engine remains stopped, no problems happens (no segfault, anything else
semes clean).

I was unable to retrieve any ALSA related ksymoops information
("ksyms <ksymoopsfiles> |grep snd" returns empty).

Could this be some kid of gcc compiler problem ? I tried the
ens1371 driver, and it works OK.

Debian SID (almost up to date).
ALSA version 0.9.0rc7
Kernel 2.4.20 + xfs
GCC: 3.2.2 20030109 (Debian prerelease)
CPU: AMD Athlon Thunderbird 1.4 GHz
256 MB RAM DDR

Any comments , suggestinos ?

bye.
