There is a segmentation fault with "modprobe hptraid". This works under RH8.0 and maybe earlier as well (can't remember back that far :-) I used to to get an oops as well: /sbin/modprobe hptraid Unable to handle kernel paging request at virtual address e002c044 printing eip: e09a378a *pde = 00000000 Oops: 0002 hptraid ataraid parport_pc lp parport autofs via-rhine mii sg sr_mod ide-scsi sc si_mod ide-cd cdrom reiserfs keybdev mousedev hid input usb-uhci usbcore ext3 CPU: 0 EIP: 0060:[<e09a378a>] Not tainted EFLAGS: 00010246 EIP is at probedisk [hptraid] 0x192 (2.4.20-8) eax: 00040040 ebx: 00000000 ecx: 00000000 edx: dffec000 esi: 00001002 edi: 00000040 ebp: 00000003 esp: db54febc ds: 0068 es: 0068 ss: 0068 Process modprobe (pid: 2960, stackpage=db54f000) Stack: 00000300 00000003 00000000 00000003 00000041 c259f680 00000300 00000000 00000000 00000000 00000000 00000000 e09a389b 00000003 00000040 00000000 00000000 00000001 00000001 e09a3000 e09a3a4e 00000000 ffffffea 00000001 Call Trace: [<e09a389b>] hptraid_init_one [hptraid] 0x47 (0xdb54feec)) [<e09a3a4e>] init_module [hptraid] 0x2a (0xdb54ff0c)) [<c011c6e1>] sys_init_module [kernel] 0x4e5 (0xdb54ff1c)) [<e09a3060>] hptraid_ioctl [hptraid] 0x0 (0xdb54ff20)) [<e09a3d78>] .kmodtab [hptraid] 0x0 (0xdb54ff2c)) [<e09a3060>] hptraid_ioctl [hptraid] 0x0 (0xdb54ff58)) [<c01093b3>] system_call [kernel] 0x33 (0xdb54ffc0)) Code: 89 4c 02 04 8b 44 24 14 8b 48 08 8b 44 24 10 d3 e0 39 c6 7c Segmentation fault I don't know what's wrong. The hptraid.c code looks the same in RH9 as in RH8. But it seg faults. The same options are passed in via grub for ide2 and ide3: ide2=0xdc00,0xe002,11 ide3=0xe400,0xe802,11 and lspci -v shows: 00:13.0 Unknown mass storage controller: Triones Technologies, Inc.

So what changed in RH9 ? I would appreciate any help or suggestions. Thank You, Paul Francis
