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


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.
