Booting 2.6.25-rc3 on my Ultra5 causes a hang before or as the console is switched over to the framebuffer. The console output is (extrapolated from dmesg in -rc2 and handwritten notes, as I don't have a serial cable to my U5): PROMLIB: Sun IEEE Boot Prom 'OBP 3.25.3 2000/06/29 14:12' PROMLIB: Root node compatible: *** the following line can't be seen in dmesg after rc2 has booted console [earlyprom0] enabled Linux version 2.6.25-rc3 (mikpe@sparge) (gcc version 4.2.3) #1 Mon Feb 25 18:49:41 CET 2008 ARCH: SUN4U Ethernet address: 08:00:20:fd:ec:1f [0000000200000000-fffff80000400000] page_structs=262144 node=0 entry=0/0 [0000000200000000-fffff80000800000] page_structs=262144 node=0 entry=1/0 [0000000200000000-fffff80000c00000] page_structs=262144 node=0 entry=2/0 [0000000200000000-fffff80001000000] page_structs=262144 node=0 entry=3/0 OF stdout device is: /pci@1f,0/pci@1,1/SUNW,m64B@2 PROM: Built device tree with 46617 bytes of memory.

Another difference is that with rc2 the first few lines of kernel output while the console is still in OF mode either aren't shown or disappear quickly since the switch to the framebuffer occurs within a fraction of a second after the kernel has been loaded. With rc3 the kernel output (the text shown above) in the OF-mode console is very very slow. (I should have quoted my .config here but I forgot to bring it. It's exactly the same in rc2 and rc3, however.) I'll try some rc2->rc3 bisecting later. /Mikael - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
