syslog is cutted

[X512]

This is hrev54051 x86_64 USB3 boot.

Syslog is always cutted and first lines are not present, it starts from some random position. When running Haiku with Qemu and stdout serial output syslog start with:

options = 0
APM version 0.0 available, flags 0.
smp: using ACPI to detect MP configuration
smp: local apic address is 0xfee00000
smp: found local APIC with id 0
smp: found io APIC with id 0 and address 0xfec00000

But there are no such content on real hardware.

Syslog on x86gcc2 SATA system. Start of syslog is present, but some stange content is present before start

This bug is causing troubles when debugging I2C driver, some syslog output of driver is not present.

Try increasing the syslog buffer size in your kernel settings file.

I uncommented syslog_buffer_size 131768 and syslog beginning is still cutted. No <DROP> or something similar is observed in syslog.

If you are using the EFI loader, it may be related to that. I have noticed that the beginning never seems to appear when using it, I don't know why.

Yes, I use EFI loader. Tablet PC do not support MBR boot.
