Hello again, >> For the R4000 there are two other things I could try: console on newport >> instead of serial port and a 32-bit kernel, which I only tried on the >> R4600. > Well, I don't know what newport is, but if it's capable of providing > output that early, it'll do. Newport is the most common graphics option for the Indy and there exists a console driver for it. Luckily it outputs some more stuff than the serial console: | CPU revision is: 00000430 | FPU revision is: 00000500 | ... | Checking for the multiply/shift bug... yes, workaround... no. | kernel panic - not syncing: Reliable operation impossible! | Configure for R4000 to enable the workaround. I configured the kernel for R4X00. There are a few references to CONFIG_CPU_R4000 in the source which doesn't seem to be a config option anymore, but I couldn't find a workaround somewhere... >> I'll also try the said patch (you're referring to "blast_scache nop ...", >> do you?). > Precisely. doesn't change anything, neither for R4000PC nor for R4600PC.
