Re: New working ia64 installer images available

[John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Hello Pedro!

I have run into the exact crash on an RX2800 on kernel 5.14.6.

However, I was able to mitigate the problem by passing

	hardened_usercopy=off

on the kernel command line.

Please give it a try with the latest images which use kernel 5.14.6 [1].
