I had looked for a known LOR matching my observations in the list, but only after sending it, I found that 033 describes the LOR, though not the panic. According to the mail threat linked to by LOR 033, a fix has been applied to -current and RELENG_5 by mlaier. But that fix did not prevent the panic I observed. The threat did contain a patch that _does_ work, though, and I hope that thios patch (even if it is only a work-around) makes it into 5.3 ... Regards, STefan
