Hello,
I have a strange problem with my USB Sound Card. I found some records using
Google, but they are all old and never answered.
I'm using the kernel module snd_uaudio to use an USB Sound Card (kldload
uaudio) on Freebsd 6.2-RELEASE. Usb Sound Card is a Hercule Muse Pocket LT.
When playing audio (using PulseAudio), after around 2 hours, I get a kernel
panic followed by a system reboot :
"19:33:14 dolphin kernel: usb0: isoc TD alloc failed"
And/Or
"Mar 30 17:56:58 dolphin kernel: panic: kmem_malloc(12288): kmem_map too
small: 42278912 total allocated".
I can reproduce it as needed.
How can we try to deal with this problem and find out what is wrong ?
Thanks for your help,
Best Regards,
Laurent H.
