           Summary: IRQ/DMA related problem with ALSA drivers on ADM64
    Kernel Version: 2.6.1-rc2
            Status: NEW
          Severity: high
             Owner: ak@suse.de
         Submitter: rjwysocki@sisk.pl

Distribution: SuSE 9.0 64-bit (x86_64) 
Hardware Environment: 2 x AMD Opteron 240, Tyan Thunder K8W, 1 GB RAM (4 x 256, two 
nodes, dual-channel), Adaptec AH19160 + 2 x SCSI HDD + SCSI CD-RW (Toshiba), 
NEC-based USB 2.0 adapter (Manhattan), GeForce FX5200 (LeadTek), SATA HDD (Seagate), 
IDE DVD (Liteon) 
Software Environment: Out-of-the box SuSE 9.0 (downloadable version) + Linux 2.6.1-rc2 
Problem Description: There is a hardware problem with the ALSA driver.  It produces no sound 
whatsoever, but there's more (from dmesg):

(The "Device not ready" stuff is probably related to SuSE-something that wants to mount the 
device.  Anyway it's present for 2.6.0 as well). 

Hint 1: seemingly, it is not present in rc1, and 2.6.0 works no-glitch ;-) 
Hint 2: it's not related to IOMMU.  It's still present after I had turned the IOMMU off in the 
kernel config. 

Steps to reproduce: Compile the kernel, install and run it.  Then try to load ALSA modules and 
play something.

they come likely from KDE, which probes two devices as default.

since the delta value (the sample count of delayed interrupt) is
small, it looks like the interrupt handling is sloppy.  if it's an
ACPI problem, usually the delta value is much bigger.
