Hi
Please mention the errata document number, looks like the attachment was dropped. Also you can just post your work-in-progress source to gerrit, including the workaround you have implemented.

Hi! I've resumed my work non ThinkPad X120e.
I have a problem with random hangs during boot. The hang occurs in vendorcode/amd/cimx/sb800/SBPort.c:296.
After a long fight I was able to diagnose the issue. It's described in errata (attached) on page 13. There is a suggested workaround, however the description is not verbose enough for me.
Could somebody give me some hints?
The functions are entered in this order: (?) cache_as_ram_setup: //cpu/amd/agesa/cache_as_ram.inc void * asmlinkage romstage_main(unsigned long bist) //cpu/amd/agesa/romstage.c void platform_once(struct sysinfo *cb) //cpu/amd/agesa/family14/romstage.c void sb_Poweron_Init(void) //southbridge/amd/cimx/sb800/early.c VOID sbPowerOnInit(IN AMDSBCFG* pConfig) //vendorcode/amd/cimx/sb800/SBPort.c (hang!)
Where should I put the workaround if I can't pollute the shared code?
The code for the port is based on asrock/e350m1. I can upload it to gerrit if needed but not much was changed.
