Dear all, I use a Digi Xem (16 serial ports) with FreeBSD Current. geclab2# kldload digi digi0 mem 0xb0800000-0xb0bfffff irq 30 at device 4.0 on pci0 digi0: Digiboard PCI PC/Xem ASIC, 16 ports found This worked ok until I updated last week. geclab2# uname -a FreeBSD geclab2.cips.mpg.de 5.2-CURRENT FreeBSD 5.2-CURRENT #0: Thu Jul 29 17:14:49 CEST 2004 krs@geclab2.cips.mpg.de:/usr/obj/usr/src/sys/GECLAB2 i386 Now every time I access any serial port on the digi I get a kernel panic. My normal (sio0, sio1) serial ports work ok. It's not always the same panic but always about mutexes or Giant etc. Here is one as an example: geclab2# cu -l /dev/ttyD0.2 panicpanic: process 530(cu):2 holds Giant but isn't blocked on a lock KDB: enter: panic [thread 100006] Stopped at kdb_enter+0x2b: nop db> where kdb_enter(c0632982) at kdb_enter+0x2b panic(c063567d,212,c20be83c,2,c0642312) at panic+0xbb propagate_priority(c1de3840,c068cc70,c0688aa0,c1de3840,c1dd8340) at propagate_pr iority+0x142 turnstile_wait(c1dd8340,c0688aa0,c20bd2c0,c0688aa0,2,c0631d0e,212) at turnstile_ wait+0x2de _mtx_lock_sleep(c0688aa0,0,c06302e4,21f) at _mtx_lock_sleep+0x11b _mtx_lock_flags(c0688aa0,0,c06302e4,21f) at _mtx_lock_flags+0x83 ithread_loop(c1de0b80,d8f6bd48,c1de0b80,c04ae198,0) at ithread_loop+0x11c fork_exit(c04ae198,c1de0b80,d8f6bd48) at fork_exit+0xa4 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xd8f6bd7c, ebp = 0 --- I'm glad for any directions. -- Robert S. <robert@mpe.mpg.de>
