At installation time, Linux finds my SCSI card (Adaptec AHA-2940U2W), tries to initialize it, then it resets the card due to timeout, no matter what method I choose for installation. In "normal" mode, if I go to the third virtual terminal (CTRL+ALT+F3) I can read: * probing buses * finished bus probing * found suggestion of aic7xxx * found aic7xxx device * found devices justProbe is 0 * going to insmod aic7xxx.o (path is NULL), and in "expert"mode I read: * 65 keymaps are available * loaded 9 keymap tables * trying to mount device hda * going to insmod aic7xxx.o (path is NULL), while in the fourth terminal (CTRL+ALT+F4) the messages are (either mode): <6> (SCSI 0) downloading sequencer code...374 instructions <4> SCSI 0: Adaptec AHA-2940U2W... <4> scsi: 1 host <4> scsi: aborting command due to timeout: pid 0, SCSI 0, channel 0, id 0, lun 0 Test Unit Ready 00 00 00 00 00 <4> SCSI host 0 abort (pid 0) timed out-resetting <4> SCSI bus is being reset for host 0 channel 0 <4> SCSI host 0 channel 0 reset (pid 0) timed out-trying harder <4> SCSI host 0 abort (pid 0) timed out-resetting <4> SCSI bus is being reset for host 0 channel 0 <4> SCSI host 0 channel 0 reset (pid 0) timed out-trying harder <4> SCSI host 0 abort (pid 0) timed out-resetting <4> SCSI bus is being reset for host 0 channel 0 <4> SCSI host 0 channel 0 reset (pid 0) timed out-trying harder .... and it gets into a loop. I am trying to put RH Linux on my machine for almost a month by now. In order to verify if there is an IRQ conflict, I have removed everything from the computer, except for the keyboard, the video card, and the SCSI card itself. If I don't have any hard disks connected to the SCSI card, the error messages are: <4> detected 1 host <4>scsi: aborting command due to timeout: pid0, scsi0, channel0, id0, lun0 Test Unit Ready 00 00 00 00 00 <4>scsi host0 abort (pid0) timed out-resseting <4>scsi bus is being reset for host0 channel0 Oops:0000 CPU:0 EIP:0010:[<c4808d9f>] EFLAGS:00010046 eax:00001074 ebx:c0fffe00 ecx:c3993078 edx:00000000 esi:c3993078 edi:00000000 epb:c481b000 esp:c01f1e94 ds:0018 es:0018 ss:0018 Process swapper(pid:0, process nr:0, stack package:c01f1000) Stack: c3993078 0000000b c48119f5 c39930ff 0e993078 000000ff c3993078 c0fffe00 00000000 00000000 c3993000 c0fffe00 00000246 c3993000 c0fffe00 c4809bf1 c3993078 00000004 c3993078 00000246 c01f1f68 0000000b 00000001 00000004 Call Trace:[<c48119f5>] [<c4809bf1>] [<c4809c29>] [<c0108a0e>] [<c01087e4>] [<c0116639>] [<c0108b13>] [<c0107b24>] [<c010634d>] [<c0106000>] [<c0106370>] [<c0107a88>] [<c0106000>] [<c0106077>] [<c0106000>] [<c0100176>] Code: 8b 47 04 0f b6 58 40 0f b6 50 42 c1 e2 03 09 d3 8d 96 e0 00 Aiee, killing interrupt handler Kernel panic: Attempted to kill the idle task! In swapper task-not syncing At this moment the system halts, and the only way to get out is to reboot. I have tested the card in all kind of Windows flavors (95/98/NT), I have installed Windows 98, then NT on the SCSI HDD ,and it worked without a problem. Steps I took towards fixing the problem: - removed any peripheral attached to the SCSI card - tried to make SCSI card's BIOS to "see" only SCSI ID#0 and the ZIP drive - removed ZIP drive, only SCSI HDD attached - installed other OS's (Windows 98, Windows NT 4.0 Server) on SCSI HDD - disable IDE buses on the motherboard (in BIOS) one by one - moved the SCSI card on each of the 4 PCI slots - removed IDE HDD's - disable almost all integrated peripherals in motherboard's BIOS - removed all peripherals (including the PS/2 mouse), excepting the keyboard, the video card, and the SCSI card. - check system's resources in Windows 98/NT to see if there is any IRQ/IO port conflict (it wasn't) - installed Linux on one of the IDE hard disks, then try to "see" SCSI card, even issued the command insmod aic7xxx (which, by-the-way, locked the system) My system has the following configuration: AMD K6-266MHz, 64MB SDRAM (one DIMM), VIA V2 chipset with 1MB cache, FIC PA-2007 motherboard (rel 1.2), Matrox Millenium II w/ 8MB WRAM, Sound Blaster Live!, Diamond Supra modem, two Western Digital HDD's on IDE 1 (2.5MB, UDMA-2, and 3.1MB),IDE CD-ROM on IDE 2, ZIP drive (ID#6) and Seagate Cheetah ST 34502LW (Ultra2 Wide-LVD, 68 pins, 4.5 GB, SCSI ID #0) connected to the SCSI controller. The BIOS assigns IRQ 11 and I/O port 6200h for the SCSI, or other IRQ (and the same I/O port) if I move the card to another PCI slot. Please help me solve the problem and have Linux installed again on my machine! Thank you.
