a shadow suddenly fell on my iMac Core Duo, and a small black window in the middle of my screen appeared requesting i reset the system--- press the power button for a few seconds.
And i did.
what madness! i broke my mac! the horror! the insanity!
ok thats putting too much into it.
what happened?
quite simple really, i was playing with Parallels 2.1 beta. i downloaded it from their website--- hoping to test out the virtualization stuff. i of course don't have a licensed copy of windows (except the one that came with my laptop, which is not being used as it is running gentoo linux), so i opted to go gentoo, my linux distro of choice. all right the system was up. gentoo live cd booted all right. i had done what any gentoo user would have at that stage, setup lan, and made my partition.
so far so good.
fdisk went well. did my mkreiserfs /dev/hda1 and did my mkswap /dev/hda2 and ran swapon /dev/hda2
all great stuff.
then i mounted /dev/hda1 on /mnt/gentoo---- all normal, all doing fine.
now the next step is fetch stage3 tar balls. now, my style is to fetch the link from via links--- and save the stage3 tarball and a portage snapshot on /mnt/gentoo, then do the necessary untar as stated on the gentoo handbook. now normally i would be at tty1 so i did control+alt+f2 to switch to tty2--- then the black screen of death appeared!!!!
after the imac restarted, i logged on to my user account and a window was waiting for me. it was an error window, asking the error to be sent to apple. now i've been using linux for quite sometime and unix pedigree is really hard to crash. i mean, fatal crash that halts the entire system kinda thingy. so why a kernel panic?!
here is the text of what was sent to apple:
panic(cpu 0 caller 0x0034FC40): freeing free mbufother stuff--- intel virtualization (core duo has the intel-vt thing running and was active when parallels was running). i had several apps running (bon echo).

anyway going back to play with parallels now. will update when more news comes back. don't know though if i could figure out why this happened. i'd certainly like to know more about it. maybe will do a google on it.
UPDATE-1 well it happened again. well this time around was certainly my fault. i force quit parallels while it was running something. and i had iTunes running in the background etc. etc. i guess the system just had too many things on ram that it went crazy. anyway, there is an excellent forums for parallels here. seems my problems has occured before. sort of.
