kernel panic (and freezes) on newer compaq and hp laptops

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: i recently purchased a compaq presario laptop, model 915us. when booting the install disks for redhat 8.0, one of two things will happen. (1) i was trying to reproduce the original problem recently and experienced a freeze-up on the "welcome to redhat linux" page. this happens with either the graphical or text mode install. this is newer behavior and perhaps resulted from having partitions already set up on the hard drive or some other change since my original install. (2) however, the original kernel panic i was seeing from the installer is still easily reproducible. currently, i have to boot with the following options: nomce nopcmcia nousb noisapnp. if i do not, i will get a kernel panic. this happens on the default 8.0 kernel as well as the newest version (2.4.18-19.8.0). the kernel panic is reported as: bank 3: b40000000000083b at 00000001fc0003b3 kernel panic unable to continue if i use just noisapnp, then it gets stuck at "mounting usb filsystem". if i use just noisapnp and nousb, then it crashes as above, just after "starting pcmcia: yenta irq list 02f8, pci irq 10, socket status 300000006 [ok]." this behavior seems exactly reproduced on a previous laptop that i gave up on--this was an hp ze4125 model. it seems that this kind of kernel panic severely limits the appeal of linux for anyone who buys newer hardware, whatever the true cause of the problem. on the hp message boards, it was claimed that this is a bios bug that is fixed by newer pcmcia-cs kernel support, but i have seen no linux release that can handle my compaq laptop properly. older models of compaq had no problem with any of this so it seems to be a defect introduced by the merger with hp. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. boot redhat install disk or 1. install redhat linux given the disabling flags above, then try booting without the flags. Actual Results: kernel panic or total freeze during install Expected Results: a normal installation of redhat without kernel panics or freezes. Additional info: see description above.
does this laptop have an radeonIGP chipset ?
yes, yes it does. currently i am just treating the radeon igp as a vesa card.
Bug 72387 has more info about getting linux to work on radeon IGP chipsets; please look there. I'll mark this bug as a duplicate of that bug to keep all info in one place. *** This bug has been marked as a duplicate of 72387 ***
this is not just a radeon igp issue. i have applied the pcmcia config.opts exclusion from bug 72387, and this makes two of the extra flags (nopcmcia and nomce) no longer necessary. however, i will still get a kernel panic if i do not include noisapnp. and i still get a freeze mounting usb filesystem if i do not include nousb. usb is a fairly important feature of the laptop which would be nice to have working; is there a bug that addresses this issue for this series of laptops? there is no isa bus on this machine (i would guess), so i don't need that, although it's bad that it will cause a crash (as described above with the kernel panic). however, usb support seems essential to have a full featured linux laptop.
radeon igp is the entire chipset, not just the graphics chip. the noisapnp appears needed because this chipset reacts rather violent to pnp probing... same for the other issues ;(
ah, okay. well, i cannot express (here, propriety prohibits it) my loathing for compaq/hp and ATI at this point. i think i shall write them a very dissatisfied letter. *** This bug has been marked as a duplicate of 72387 ***
i have the same problem with compaq evo n1005v there is the solution for this problem kerne panic with red aht 8.0
