Only after buying (aftermarket) + one time when I was installing (for the first time) kernel-power with backupmenu-multiboot, and failed to prepare correct multiboot entry (resulting in that old amiga's reference "guru meditation error").

Other than that, I restored backupmenu image once, due to filesystem corruption via bad undervolting settings. Other than that, never got any problems. I think it's a matter of knowing what You install/modify, + not using "placebo" magical "patches", + doing overall sane things.

By the way, with correct treatment (swap refreshed to avoid fragmentation), device is as fast and responsive after week+ uptime, as just after boot.
