Package: xen-hypervisor-4.11-amd64
Version: 4.11.3+24-g14b62ab3e5-1~deb10u1
Severity: important
Dear Maintainer,
After updating to Buster and Xen 4.11 our machine no longer boots the Xen kernel. The default kernel 4.19.118-2+deb10u1 boots normally.
The machine has an Areca 1882IX-16 card in it when the arcmsr module
tries to load the following error appears.
Areca RAID Controller0: Model ARC-1882, F/W V1.56 2019-07-30
arcmsr0: dma_alloc_coherent got error
No drives are discovered and the initramfs prompt is shown.
The machine:
* Supermicro X9DRW
* Dual Intel(R) Xeon(R) CPU E5-2630L v2 @ 2.40GHz
* 128G RAM
* Areca ARC-1882IX-16 (1G onboard cache)
Nothing I have tried is effective:
* Turning on BIOS above 4G decoding stops the Intel 10GBE ixgbe driver from functioning and doesn't fix the arcmsr
* Unloading and reloading the arcmsr module from initramfs prompt
* Downgrading the Areca 1882 bios to v1.52 as per http://faq.areca.com.tw/index.php?action=artikel&cat=7&id=902&artlang=en
* Kernel parameters
** pci=nocrs
** dom0_mem=8G
** mem=3072M
** mem2048M cma=1024M
** cma=2048
** cma=3076 at 512M
** iommu=1 intel_iommu=1
** arcmsr.host_can_queue=64 as per http://faq.areca.com.tw/index.php?action=artikel&cat=15&id=387&artlang=en
I expected the arcmsr module to load and detect disks as it does with
the stock kernel.
I can provide sysctl and dmesg output if it helps.
