Bug #1426

Updated by tuxillo 7 months 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

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