I apparently forgot to apply the mm1 patch before compiling it.
I got a BUG, which I could write down by getting X out of the way first. It is repeatable, just ask if I omitted something cruical. On bootup, the verbose debugging complains about read errors on sdc, I guess the kernel tries to get the partition table. I have no idea why there is read errors - that shouldn't hang anything though. To bring it down: dd if=/dev/sdc of=sdc.dump bs=1M sd 0:0:0:2 ioctl_internal_command return code: 8000002 :Current: Sense key: Hardware Error Additional Sense: End_of_data detected cut here---- Kernel BUG at [Verbose debugging unavailable] invalid opcode: 0000 [#1] cpu:0 EIP: 0060:[<c031f823>] Not tainted VLI Eflags: 00010002 (2.6.16-rc1 #16) EIP is at start_unlink_async eax:00000000 ebx:dfe69180 ecx:e0832020 edx:00000005 esi:dffdb6bc edi:00010021 ebp:dffdb6bc esp:c0664d58 ds:007b es:007b ss:0068 Process swapper . . . stack . . .

The crash is trivial to reproduce, just ask me.
