snd_usb_audio OOPS on MIPSEL - is that the mmap issue?
From: Andreas Mohr
Date: Wed Nov 25 2009 - 18:12:25 EST
Hi,
when running
cat X.mp3|madplay -
on my ASUS WL-500gP v2 Debian 2.6.30.9, I get lots of "Problems" (tm),
with a backtrace that looks related:
[<80090c10>] swap_info_get+0x74/0xfc
[<80093090>] free_swap_and_cache+0x20/0x220
[<80083480>] unmap_vmas+0x418/0x63c
[<80087c3c>] exit_mmap+0xb8/0x148
[<8002d5c0>] mmput+0xbc/0x1d4
[<800325fc>] exit_mm+0x260/0x298
[<8003491c>] do_exit+0x1cc/0x6a0
[<80014034>] nmi_exception_handler+0x0/0x34
This would perhaps be the MIPS mmap issue
(see e.g. http://patchwork.kernel.org/patch/60430/ ), right?
Oh well, b44 netconsole lockup (just fixed it),
non-working WLAN (seems most close to fully working after all,
incredible as that may be given my initial thoughts),
crashing usb-audio, non-transferring ftdi_sio.
Does anything actually WORK on this box at all???
That's almost a worse status than my Aspire One A110L once had...
(and that's saying a LOT given that that one had more than 10 issues).
It will get better eventually, I'm sure...
Thanks,
Andreas Mohr
