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.
