Created attachment 236691 [details] dmesg output command of the working FreeBSD 12.3p6 Using the instructions at https://www.freebsd.org/releases/13.1R/installation/ following: Upgrading Using "FreeBSD Update", the system hangs after rebooting in the new kernel. The system boots, but at the console, repetitiously print the message: "CPU0: local APIC error 0x4" I can only switch off the PC. I have tested booting the system with these two images: FreeBSD-13.1-STABLE-i386-20220819-6ecf086d5a0-252127-mini-memstick.img FreeBSD-14.0-CURRENT-i386-20220819-545db925c3d-257513-mini-memstick.img but it hangs with the above message. Attached the output of the dmesg command of the working FreeBSD 12.3p6
Kostik did a lot of work on i386 architecture code, perhaps he may have an idea of what's going wrong.
I have tested the latest i386 snapshot. I have downloaded: FreeBSD-14.0-CURRENT-i386-20220930-42dc8696df5-258315-bootonly.iso FreeBSD-14.0-CURRENT-i386-20220930-42dc8696df5-258315-mini-memstick.img and put on a CD and USB stick respectively. On the Soltek Qbic with an AMD Athlon XP 2000+, the PC where I have found this error. Booting from the USB stick it gives the previous error: the system boots, but at the console, repetitiously print the message: "CPU0: local APIC error 0x4" For this error I have found a pair of running old PC. A Fujitsu Siemens with Intel Pentium 4 CPU 3.06 GHz. Booting from CD it panics after printing the message: panic: ata_action: cbb 0x119431b0, func_code 0x901 should not be allocated from UMA zone Should I open a new bug ? An ASUS P4 with Intel Pentium 4 CPU 2.00 GHz. It boots from the CD and can reach the login prompt.
On the Soltek Qbic with an AMD Athlon XP 2000+, booting an USB stick with FreeBSD-13.2-BETA2-i386-mini-memstick.img gives the same error: at the console, repetitiously print the message: "CPU0: local APIC error 0x4"
On the Soltek Qbic with an AMD Athlon XP 2000+, booting an USB stick with FreeBSD-14.0-BETA3-i386-mini-memstick.img gives the same error: at the console, repetitiously print the message: "CPU0: local APIC error 0x4"
On the Soltek Qbic with an AMD Athlon XP 2000+, booting an USB stick with FreeBSD-14.0-BETA4-i386-mini-memstick.img gives the same error: at the console, repetitiously print the message: "CPU0: local APIC error 0x4"
I got over this problem by setting the following, either as parameter to the kernel (press Esc) while booting from memstick: set hint.apic.0.disabled="1" boot And then, adding hint.acpi.0.disabled="1" to /boot/device.hints.
