I'd used: OpenBSD 5.8-current (GENERIC) #799: Wed Nov 18 01:34:20 MST 2015 > but I still had the following panic: > > panic: psycho0: uncorrectable DMA error AFAR 663f8450 (pa=0 tte=0/6218a012) > AFSR 410000ff40800000 Damn! although this was stable for a couple of hours yesterday (and that's quite an improvement to how it was) - today I booted it up and it crashed on my very first SSH login attempt. Thank you for re-testing anyway. I notice your machine crashed in process sshd also. My backtrace looks slightly different to yours so I share it here: panic: psycho0: uncorrectable DMA error AFAR 6e868448 (pa=0 tte=0/69a12012) AFSR 4100ff0020800000 Stopped at Debugger+0x8: nop TID PID UID PRFLAGS PFLAGS CPU COMMAND *13074 13074 0 0x12 0 0 sshd psycho_ue(400008a3200, 0, 4000fb13bc8, 0, 0, 0) at psycho_ue+0x7c intr_handler(e0017ec8, 400008a3300, 58c86, 4000fb13cd8, 1, 0) at intr_handler+0xc sparc_interrupt(0, 4000fb13db0, 4000fb13df0, 0, 0, 14b) at sparc_interrupt+0x298 syscall(4000fb13ed0, 404, 1cd56442e8, 1cd56442ec, 0, 0) at syscall+0x34c softtrap(3, 1c49412ee4, 54, 0, 0, 0) at softtrap+0x19c http://www.openbsd.org/ddb.html describes the minimum info required in bug reports.
