Hello all, In the past couple of weeks, I've been getting pretty regular crashes and reboots on one of my machines (dmesg attached). I tried to cvsup it to the latest -CURRENT, but I kept getting strange assembler and cc errors during make buildworld, and they were never the same. Not too fond of beating my head against a wall, I just reinstalled the machine from scratch using the 20000820- CURRENT snapshot and compiled a custom kernel with 'options DDB'. I'm still experiencing sudden reboots, especially during large writes, but it's inconsistent. I'm convinced that it's hardware- related, but I don't know which piece (I've already replaced both memory and motherboard to no avail) to blame. This morning, I received the following panic, and the machine dropped into debug (Please forgive any spacing or form errors, as I had to copy this all down by hand): panic: pmap_release: freeing held page table page mp_lock = 01000001; cpuid = 1; lapic.id = 00000000 A trace yielded: Debugger(c0291ff2) at Debugger+0x34 panic(c02afd60,c06f0b2c,d36b548c,43,c015f4ee) at panic+0xa4 pmap_release_free_page(d36b548c,c06f0b2c) at pmap_release_free_page+0xa4 pmap_release(d36b548c) at pmap_release+0x5b vmspace_free(d36b5420,d36b06c0,d36b06c0,d7196f14,c015bb1b) at vmspace_free+0x6d cpu_wait(d36b06c0) at cpu_wait+0x15 wait1(d36b0a00,d7196f80,0,d7196fa0,c0270e4d) at wait1+0x2bb wait4(d36b0a00,d7196f80,bfbffb58,1,80c1000) at wait4+0x10 syscall2(2f,2f,2f,80c1000,1) at syscall+0x219 Xint0x80_syscall() at Xint0x80_sycall+0x2b Does this help identify the culprit? Any help would be greatly appreciated. -- Regards, Evan Tsoukalas Systems Administrator Source Electronics Corporation [EMAIL PROTECTED]
