@noahmehl do you have an environment you can test with? If you can confirm the patch I linked works, I can work towards getting into the GA ubuntu kernels. I built test packages including the patch based on latest ubuntu 22.04 kernels (regular and hwe) here:

It seems the patches were never merged upstream. However there is a recent patch that is much simpler and appears to directly address this: https://lore.kernel.org/linux- bcache/20231128211001.877333-2-sas...@kernel.org/ It is already in master and the latest 6.7 release candidate (RC4) so we

Yes, will look to backport after it is merged upstream. No ETA for now, but hoping the upstream merge will happen in the next week or two based on response from Coly Li [1]. [1]https://lore.kernel.org/linux- bcache/58af801b-9f98-4cf1-9db3-7a631e381...@suse.de/ -- You received this bug

The failure occurs as a result of a new allocation check (for kvmalloc_node) that was added between 5.9 and 5.15+ https://github.com/torvalds/linux/commit/7661809d493b426e979f39ab512e3adf41fbcc69 It also requires two conditions: 1. The drive presents an optimal IO size > 0 (checked at

Thanks Joel, the firmware you posted worked for us. I will note we have the HBA330 mini, which has it's own distinct upgrade file as opposed to the regular HBA330. HBA330 mini: https://www.dell.com/support/home/en-au/drivers/driversdetails?driverid=124x2 i'm still a bit puzzled why a firmware

Hello Timo, Did you find a solution to this problem? We are seeing the exact same scsi errors on our dell servers with H330 controller as well, on 18.04, 14T drives. We have installed RHEL7 on other exact same spec servers, but the issue is not present so it might be particular to Ubuntu and/or
