Re: SMP SS10 freezes hard intermittently

The existing OS on the disks was SunOS 4.something, which was not amused to find a second CPU. As I expect you saw, Anton Blanchard suspects that this sort of unpleasantness is to be expected from a 2.2 kernel, so I'll either just be patient, or continue shotgun debugging. Thanks- David

Re: SMP SS10 freezes hard intermittently
I've got an SS10 with two CPUs, running a 2.2.15 kernel with SMP enabled. It locks up hard periodically, and won't respond to stop-A, a break on the serial port, the three-fingered salute, or, in fact, anything short of a power-cycle. When I was fixing sparc32 SMP in 2.2, I only had access to one cpu and machine type (viking supersparc on 4m/690).
