I wonder what exactly was the bug? As far as I can google it's not been made public. https://www-ssl.intel.com/content/dam/www/public/us/en/docum... (errata for the CPU I have, and I just tested and the TSX instructions aren't disabled on it btw. I probably enabled TSX in BIOS and forgot about it) mentions minor issues with string instructions' interaction with TSX, rdrand having a chance of hanging if called within a transaction, but the bug blamed for the disabling of TSX (HSW136) is just described as "unpredictable system behavior" "under a complex set of internal timing conditions and system events".
