Hello,

I'm currently having troubles while trying to listen or rip cds audios.
`cdparanoia -Q` works fine
but `strace cdparanoia 1` hangs at :
ioctl(3, 0x530e

Then I have from `dmesg` :
hdc: lost interrupt
hdc: lost interrupt
(...)
hdc: lost interrupt
hdc: lost interrupt

The only thing I found in archives is :
" It seems like the 'lost interrupt' while
ripping audio CDs is specific to VIA based motherboards."

In fact, I have a VIA based motherboard :
VIA KT333 and VIA 8233A

I'm using Linux version 2.4.21 (gcc version 3.2.2) #2 Thu Jul 3 12:42:17
CEST 2003

Some infos from /proc/ide/ide1/hdc :
driver: ide-cdrom version 4.59-ac1
model: CRD-8322B
settings :
name value min max mode
---- ----- --- --- ----
breada_readahead 4 0 127 rw
current_speed 34 0 70 rw
dsc_overlap 0 0 1 rw
file_readahead 0 0 2097151 rw
init_speed 12 0 70 rw
io_32bit 1 0 3 rw
keepsettings 0 0 1 rw
max_kb_per_request 64 1 127 rw
nice1 1 0 1 rw
number 2 0 3 rw
pio_mode write-only 0 255 w
slow 0 0 1 rw
unmaskirq 1 0 1 rw
using_dma 1 0 1 rw

I tried setting using_dma 0, unmaskirq 0.
Otherwise, my cdrom works perfectly for data cds.

Please help me
