Hello List, I have a Dell PE 4600 with 24MB of memory that I am trying to run 6.2-RELEASE-p7 compiled with the standard PAE config file. I get the following at boot: (hand copied) 6.2-RELEASE-p7 root@....:/usr/src/sys/i386/compile/PAE acpi_alloc_wakeup_handler can't alloc wake memory ACPI APIC Table : <DELL PE4600 > timecounter "i8254 frequency 1193182 Hz quality 0" CPU: Intel(R) Xeon(TM) CPU 3GHz (2990.33-MHz 686-class CPU) Features=0xbfeb8bff <FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTTR,PGe,MCA,CMOV,PAT, PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0c4400 <CNTX-ID,<b14>> Real Memory = 25769803776 (24576 MB) kmem_suballoc : bad status return of 3. panic: kmem_suballoc Uptime: 1s The box seems to run fine if I don't try use PAE. It is a dual cpu box and without PAE it does not seem to have a problem running SMP. I have tried both the standard PAE config and the standard PAE config with Option SMP. Both fail.

Remote host said: 553 Dynamic pool 84.21.226.46. <http://unblock.secureserver.net/?ip=84.21.226.*> Giving up on 64.202.166.12. I have visited the link and made a request to unblock our smtp server but it hasn;t been done yet. So, i send it to stable list with attachments :) -- Artem -------------- next part -------------- A non-text attachment was scrubbed...
