Any fairly recent 3.0-current. The problem is
reproducible on 3.0-RELEASE as well as on -current
as of 1999-01-14 (yesterday).
>Description:
This is a PentiumII-450 with 512 MB RAM, equipped with
an SB AWE64 soundcard (ISA). When using the Voxware
drivers, we get:
snd0: <SoundBlaster 16 4.16>
soundcard buffer alloc failed
snd: Unable to allocate 131072 bytes of buffer
When using the new "Luigi" pcm driver, there is no such
error message, but the soundcard still does not work --
as soon as we try to play something, we get:
panic: isa_dmacheck: no physical page present
The soundcard is correctly configured. As soon as we
remove any one or more of the memory DIMMs (thus
reducing the amount of RAM to less than 512 MB), the
soundcard does work fine.
I searched the mailing lists and found another one with
the same problem (Soundcard DMA doesn't work with 512
MB RAM), but neither a fix nor an "official" PR.
The lnc NIC driver seems to be affected, too. There's
a 10Base-FL PCI card (based on some AMD chip) in that
machine, which does not work with 512 MB RAM, but does
work (although slow) with anything less than 512 MB.
All other hardware works fine with 512 Mb: Adaptec
7890 U2W host adapter, 100Base-FX NIC (based on intel
82557 chip, probed as EtherExpress Pro/100B), another
EtherExpress which is onboard of the mainboard, Matrox
Millenium G200 (AGP), floppy drive.
Here's the boot output of that box, and the kernel
config file. Let me know if you need more information.
