Re: [SUPERH / PATA / SCSI] Unable to do start userland after kernel boot

[Kristoffer E. <kri...@gm...>]

Greetings,

I made another BAD kernel just to make sure that generic was inside it,
turns out the new bad kernel gives out : sd 0:0:0:0: Attached scsi generic
sg0 type 0 and still fails.
My mistake for not compiling the latest bad kernel myself.
So back to square one then I guess.

I did a small bisect last night going through arch/sh only and it didn't
produce any workable kernel, so atleast that implies the error lies
elsewhere.
Will see if I can bisect all changes and see where I end up.

Though:
ata1: PATA max PIO0 mmio cmd 0x150001f0 ctl 0x150001fe irq 77 this line
still contains "+mmio" when compaired to the good kernel. Not sure if that
actually reflects anything since we were using mmio long before, but perhaps
didn't inform about it at bootup.

Thanks for commenting paul
