bce_vhci errors with Linux 5.8.10

[tobiwild]

My Hardware: MacBookPro16,1

After upgrading from kernel 5.7.17 to 5.8.10 the apple-bce module doesn't work for me anymore. I get the following error:

As recommended in https://github.com/aunali1/linux-mbp-arch/issues/22 I load the module before any hooks are run:

MODULES=(apple-bce)
HOOKS=(base udev autodetect modconf block keyboard encrypt filesystems fsck)

The keyboard works while entering the password to decrypt the filesystem, after that I get the errors from above and the computer shuts down after a while.

@tobiwild try to remove the old kernel from boot folder also from modules

Edit: also remove Apple-bce from all kernels using --all option then reinstall it and don't forget to mkinitcpio -p Linux-mbp reboot after adding Apple-bce to mkinitcpio.conf

[tobiwild]

Thank you, but I did all that :) It worked perfectly on 5.7.17 and I now updated to 5.7.19, where it also works. Only on 5.8.10 I have these issues (I tried with DKMS and Non-DKMS versions of apple-bce)

[Ahmed97i]

I have MacBookPro 15,1 with kernel 5.8.10-1-mbp it is not very stable sometimes it crashes during boot but works fine N.B.: be sure to include only apple-bce module in mkinitcpio.conf file

I have the exact same issue.

• MacBookPro15,2.
• Kernel from here: https://github.com/aunali1/linux-mbp-arch version 5.8.13-1-mbp.
• bce from here: https://github.com/aunali1/apple-bce-arch version a96d0bcf8d1f1a64eff7d69f8132222bb233f094

bce_vhci_urb_dequeue 81 spammed by kernel and then a general protection fault in the kernel. Did not try other kernel versions, this is my first attempt on a Linux install on my mac. It does not seem to matter if I load apple-bce in initramfs or later, but the crash happens after final rootfs is mounted. As opposed to OP, my keyboard does not work in initramfs.

Probably a duplicate of https://github.com/aunali1/linux-mbp-arch/issues/26. I will try to downgrade kernel to 5.7.17-1.

Update: Downgrading to 5.7.17-1 works for me.

I am on a MacBookPro15,1 and had this issue when using linux-mbp kernels 5.8.x. Upgrading to linux-mbp 5.10.12 fixed this issue for me.

[TRPB]

@aunali1 is there any chance of putting the latest kernel in your https://packages.aunali1.com/archlinux/mbp/x86_64/ repo? It's really convenient just getting it from there since it's not in the AUR.

[networkException]

The repository moved to https://dl.t2linux.org (see step 7 and 9 in https://wiki.t2linux.org/distributions/arch/installation/)

[TRPB]

ah thanks!

[aunali1]

@metaspace @tobiwild Please update to the latest version of apple-bce and linux-mbp as some of the above problems have been rectified.
