---------------------------------------- Bug #386: ASUS P8Z77-V LX2 - Raminit issue at second boot with two 8GiB DIMMs - bootloop https://ticket.coreboot.org/issues/386#change-1360
* Author: gzz5f gzz5f * Status: Closed * Priority: High * Category: board support * Target version: master * Start date: 2022-06-05 * Affected versions: master * Needs backport to: none * Affected hardware: ASUS P8Z77-V LX2 * Affected OS: all ---------------------------------------- I build coreboot today for the ASUS P8Z77-V LX2 and used the latest coreboot master code.
The 2 8GiB DIMMs are working fine at first boot. You can start computer, install from a live media the OS and so on. But at the second boot it failes boot forever and its bootooping. It does not make a change if i boot for a second until SeaBIOS output and then turn off the computer or use the computer for longer time. The second boot is always broken. Workaround 1: Remove one of the two 8GiB DIMMs. Then the computer also starts fine after a reboot. Workaround 2: Install two 4GiB DIMMs instead of two 8GiB DIMMs. Then the computer also starts fine after reboot. Workaround 3: At every boot boot for a second with one DIMM. Turn off the computer, insert the second DIMM and start it again.
kmalkki told me to rebuid the image with DEBUG_RAM_SETUP=y
I then build a second image, with DEBUG_RAM_SETUP=y. The logfile contains the first successfull boot (created with Workaround 3), the poweroff and the poweron with the bootloop. I have let it bootloop few times before turned off the PSU.
