Bug #1426

Updated by tuxillo almost 11 years ago

While running stress2 using trevorjk's vkernel setup with the 
     
     latest head as of last night (after my second round of pthread 
     
     fixes for the vkernel) I got a mbuf panic: 

     

     panic: m_copydata, negative off -1 
     
     mp_lock = 00000001; cpuid = 1 
     
     Trace beginning at frame 0x57a9ea04

     The vkernel is bring run on my 2xCPU test box, configured -n 2 -m 128m.
