Could you be more verbose?

What errors you need to dump?
I don't think that there is such combination.

You can just turn on all debug level at boot, passing to kernel
specific options, I do it next way:
In "/etc/default/grub"
Add or replace or join with yours
GRUB_CMDLINE_LINUX_DEFAULT="noapic ignore_loglevel debug
debug_locks_verbose=1 sched_debug initcall_debug mminit_loglevel=4
udev.log_priority=8 loglevel=8 earlyprintk=vga,keep log_buf_len=10M
print_fatal_signals=1 apm.debug=Y scsi_logging_level=1
usbserial.debug=Y option.debug=Y pl2303.debug=Y firewire_ohci.debug=1
hid.debug=1 pci_hotplug.debug=Y pci_hotplug.debug_acpi=Y
shpchp.shpchp_debug=Y show_lapic=all hpet=verbose lmb=debug
pause_on_oops=5 panic=10"
