Hi Gerard + Linus + linux-kernel,
I grabbed the pre 2.0.1 #2 patch, applied against 2.0.21 disabled FORCE_NORMAL_IO since vremmap() is fixed and rebooted...
ncr53c810-0: using memory mapped IO at virtual address 0xc2833f00 Unable to handle kernel paging request at virtual address 82833f04 current->tss.cr3 = 00101000, %cr3 = 00101000 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<c01a0d25>] EFLAGS: 00010202 eax: c2833f00 ebx: 00000f00 ecx: 0008adb0 edx: 60000000 esi: c0088068 edi: ffbe7f00 ebp: c0088018 esp: c033eebc ds: 0018 es: 0018 fs: 0018 gs: 0000 ss: 0018 Process swapper (pid: 1, process nr: 1, stackpage = c033e000) Stack: c01dcd2c 00000001 00000001 ffffffff c2833000 00000f80 c00f7001 00000001 c01a55c0 c01dadc0 00000000 00000001 00000001 0000032a ffbe7f00 0000fc00 0000000c 00000000 00000070 00000000 00000000 00000000 00000000 c01d000f Call trace: [<c2833000>] [<c01a55c0>] [<c01a5295>] [<c019a034>] [<c0198398>] [<c016f3f1>] [<c012d78c>] [<c010a51b>] [<c011e090>] [<c0109386>] [<c01091b4>] [<c01091bb>] [<c010933c>] Code: 8a 80 04 00 00 c0 eb 0f 8d 76 00 66 86 96 78 0f 00 00 66 83

Still exactly the same than yesterday. I know, Gerard, that you are working on it, i am disposed to try patches, crash my HDD, etc.
