Re: problems with gcc 3.2.2 update

[Manuel Jander <mjander@embedded.cl>]

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.
