We've been using Turnkey Linux Bugzilla 18.104.22.168-2+lenny2 for a while now and so far are very happy with it. Due to a feature that exists in Bugzilla 3.2 and up, I deployed the latest Bugzilla 11.1 x86 on a separate VM. I noticed that whenever powered on under a 64-bit ESX host, the TKL Bugzilla OS segfaults and the boot sequence drops to an initramfs shell. If I migrate it to a 32-bit host, it runs just fine.
Next week we are planning to perform the tranistion to the new Bugzilla, however our production ESX is a 64-bit host. I guess it worth to menion that our 64-bit hosts are running other 32-bit OSes just fine. It seems that it only TKL 11.1 x86 is bothered by it.
Thanks in advance
