I have the same issue. After change to gzip compression, it properly boots. With bzip2 or lzma, i got: baryluk@sredniczarny:/sctank2/Dane/linux/linux-2.6/linux-2.6$ md5sum ./arch/i386/boot/bzImage ; qemu -kernel ./arch/i386/boot/bzImage 8ff875e103dbe7f88c344f3a91f0d3fa ./arch/i386/boot/bzImage qemu: fatal: Trying to execute code outside RAM or ROM at 0x3133feb0 EAX=3133feb0 EBX=3128b000 ECX=00000000 EDX=00000000 ESI=00000000 EDI=3128affc EBP=00100000 ESP=317425c0 EIP=3133feb0 EFL=00000002 [-------] CPL=0 II=0 A20=1 SMM=0 HLT=0 ES =0018 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] CS =0010 00000000 ffffffff 00cf9b00 DPL=0 CS32 [-RA] SS =0018 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] DS =0018 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] FS =0018 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] GS =0018 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] LDT=0000 00000000 00000000 00008200 DPL=0 LDT TR =0020 00001000 00000067 00008900 DPL=0 TSS32-avl GDT= 00012bb0 00000027 IDT= 00000000 00000000 CR0=60000011 CR2=00000000 CR3=00000000 CR4=00000000 DR0=00000000 DR1=00000000 DR2=00000000 DR3=00000000 DR6=ffff0ff0 DR7=00000400 CCS=0005b2e0 CCD=0002d970 CCO=SARL FCW=037f FSW=0000 [ST=0] FTW=00 MXCSR=00001f80 Last commit dd59f6c76b265ed2ff18b497d6105a9511b1feb1 All other CONFIG_* options was excluded, leaving minimal possible kernel.

The kernel fails to boot if compressed with bzip2 or lzma, gzip works.
