Dri= ver developed in house for ISS simulations. Works fine on 5.3 and prior kernels. Works fine with 5.11 if not using shared IRQ's. No interrupts with shared IRQ's. Machine is a HP dl580 G9 w/ 72 Intel(R) Xeon(R) CPU E7-8867 v4 @ 2.40GHz. We only have a few of these machines the rest are G10's and work fine (not sharing IRQ's with timing cards). I am having the card moved to another slot to try and get a unshared IRQ. Unfortunately MSI does not seem possible with this card.

For what hardware platform? And what kernel version worked for you and now does not work? thanks, greg k-h -- You may reply to this email to add a comment.
