Hi! After seeing Michael Schmitz's patch for 2.6.19 I tried it ( http://marc.theaimsgroup.com/?l=linux-m68k&m=116585861312099&w=2 ) and it fixed the ide0 IRQ problem. However now my system ends up with the following: Linux version 2.6.18 (standa@oxygen) (gcc version 3.4.5) #29 Tue Jan 23 21:38:51 EST 2007 Atari hardware found: VIDEL STDMA-SCSI ST_MFP STND_DMA YM2149 PCM CODEC DSP56K ANALOG_JOY Blitter tried to read byte from register ff8a00 at 00770e BLITTER IDE TT_CLK FDC_SPEED DIB_SetVideoMode: SDL_windowid 0 SDL_windowX 157, SDL_windowY 176 DIB_SetVideoMode2: SDL_windowid 0 SDL_windowX 157, SDL_windowY 176 DIB_SetVideoMode3: top -2 x 154, y 154 Detected scancode offset = 0 (key: 'space' with scancode $39) Built 2 zonelists.

This is Petr Stehlik's etch.img (from http://web.zln.cz/~joy/etch.img.gz ) referred to by this page http://wiki.aranym.org/manual#linuxm68k_on_aranym . Also there is something I didn't mention before. The Tux logo is somehow corrupted unlike in Petr's 2.4.27 build. I am sure this is due to my ignorance to the Linux kernel development in the last 2 and half years where I haven't used it on daily basis and that it most probably doesn't belong to this list... Anyway, can somebody help with this? Thanks! Standa Note: this time I have attached the all.config ;)

Let me introduce myself here as I have never contributed to this list before. My name is Standa Opichal and I am one of the guys from the ARAnyM team who was mostly working on the native FreeMiNT drivers for the emulator. I have been trying to build the 2.6.8-18 from the debian server provided linux-2.6_2.6.18.orig.tar.gz and linux-2.6_2.6.18-8.diff.gz. I am using crosstool-0.43 provided crosscompiler (gcc-3.4.5-glibc-2.3.6, see below for more details if needed). I wasn't completely sure about how to configure the source to build with the aranym extensions and so I used slightly modified debian/arch/m68k/config.atari as the all.config and run the 'allnoconfig' target to get complete .config (my all.config is attached). The build was successful and I am able to get aranym (the latest CVS version) booting the kernel. However I got some kernel panic and after few added lines I have got the output below where it seems that the IRQ 15 is already taken (failing on request_irq() in init_irq() in drivers/ide/ide-probe.c around line 1120 - see the complete output below). As I have no experience in Linux kernel hacking yet (this is hopefully going to change) I would kind like to ask you for some guidance like what to try next, some URLs to get the real bleeding edge sources and patches if that was fixed/changed. I just hope I am not too ignorant to local rules and that this mail is just a starting point for our further cooperation.
