Kernel Panic Issues after installing 2.0.0 RC5 on Big Sur

[Jimbo]

Ok, in the Parallels VM, this build seems servicable, however, I've installed it on some real tin too (older MBP). Panic on boot (again, no keepsyms, sorry):

Code: Select all

panic(cpu 6 caller 0xffffff80003efa76): Kernel trap at 0xffffff7fa1a39702, type 14=page fault, registers:

Woah... weird.

I booted into Safe Mode to get the previous kernel panic and disable the zfs.kext. I then booted into Recovery Mode to set keepsyms etc via nvram boot-args, did that, renabled the zfs.kext and then rebooted.

Thing is, laptop has booted successfully, kext is loaded and I've imported a pool!

Thoughts?

Cheers!

And... then it went bang! Doing some reasonably intensive file IO:

[lundman]

Ah so - is there a problem, or appears to (not panic) ?

admittedly, it's pretty hard to get rid of a kext once it is in there. BigSur sure likes to keep loading them.

Very similar panic emptying the trash of the pool (which contains only Xcode 12.2):

Edit: Spelling

[Jimbo]

Ok back to weird...

If I clear my boot-args, I'm back to panics on boot. Specifically, it seems that if I set (via Recovery Mode):

Code: Select all

nvram boot-args="keepsyms=1 debug=0x146"

Things boot and work-ish (see panics above). Clear boot-arg and back to very b0rked.

Edit: yep, validated again - clear boot-args = panic on boot, set boot-args as above = boot and [kinda] working pool (but breaks under [delete] load).

Cheers!

It's repeatable across multiple systems. I tried doing as you discovered and can load the kernel extension without the page fault panic.

If I clear my boot-args, I'm back to panics on boot. Specifically, it seems that if I set (via Recovery Mode):

Code: Select all

nvram boot-args="keepsyms=1 debug=0x146"

Things boot and work-ish (see panics above). Clear boot-arg and back to very b0rked.

I've not had a panic yet... but my pool is wonky. I can see my pool and 1 (of 3) volumes on the pool. /dev/disk12 should have a partition schema, an EFI partition, and then an Apple_HFS partition. I'm missing what would probably be disk14 (which should have the same basic structure - GUID schema, EFI, then Apple_HFS partition)

Code: Select all

/dev/disk11 (internal, virtual):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        +54.7 TB    disk11
   1:                ZFS Dataset ⁨zfsPool⁩                 54.7 TB    disk11s1

/dev/disk12 (external, virtual):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                                                   +5.5 TB     disk12

/dev/disk13 (external, virtual):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        +1.6 TB     disk13
   1:                        EFI ⁨EFI⁩                     209.7 MB   disk13s1
   2:                  Apple_HFS ⁨Photos & Videos⁩         1.6 TB     disk13s2

I also had panics any time I tried to boot. The reports were like the ones posted above, so I won't repeat them.
I had to boot in safe mode and uninstall to be able to login on the next reboot.

For anyone who wants to uninstall, note that the wiki uninstall instructions talks about starting from the dmg.
This install is from a pkg file and I had to use

Code: Select all

pkgutil --expand /Users/michel/.Trash/OpenZFSonOsX-2.0.0-Big.Sur-11.0.pkg package

The the command I used to uninstall was

Code: Select all

sudo package/my_package.pkg/Scripts/preinstall_actions/0uninstall

It would help immensely if you could have keepsyms=1 so we can see the stack on panics. Especially for the "panic instantly on boot" problem. That is generally when we run benchmarking on all the new assembler replacement functions.

As for uninstalling, you should reboot into Recovery, start Terminal, and run:

# kmutil trigger-panic-medic --volume-root=/Volumes/NAMEOFYOURDISK

then reboot normally, and once up, "rm -rf /Library/Extensions/zfs.kext" and it is gone. You will have to "approve" any other 3rd party kexts again.
