https://bugzilla.kernel.org/show_bug.cgi?id=214789 --- Comment #2 from Scott Arnold (scott.c.arnold@xxxxxxxx) --- Hello, The driver is for a Symmetricom bc635pcie Time and Frequency Processor. Driver 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.
