"Syncing disks" is just a message, telling you, that the kernel is synchronizing in-memory disk cache with hard drives. If it is a laptop, try booting it with different apm / acpi settings. To tweak those settings, you should enter kernel configuration utility at boot time (when "booting kernel in 10 seconds" message shows up, type "boot -c", then "visual") - in 4.x. 5.x series has this done somewhat different. I don't know if that Acer PC of yours has known issues - but in general, if kernel panics occur randomly, this is propably a symptom of CPU overheating - or bad random-access memory (RAM) chips. You can test your RAM using free software from http://memtest86.com (please note, that you should run this test at least for several hours if it doesn't break at once - some RAM chips show errors only when they worked for a some time, so their temperature is higher, than normal). Also, BIOS RAM timings matter in this case - if you can change it, lower it a bit. HTH, -- mp
