From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021130 Description of problem: Kudzu causes a kernel fault on redhat 8.0 when installed on a Sony Vaio PCG-881R laptop. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Get a relatively new sony vaio laptop (pentium III based) 2. Install redhat 8.0 3. Watch in horror as kudzu makes the freshly installed laptop crash and burn. Actual Results: Kudzu causes a kernel Oops: 0002 error and the computer locks up shortly afterwards. The error message is as follows: Checking for new hardwareOops: 0002 ohci1394 ieee1394 ide-scsi scsi_mod ide-cd cdrom mousedev keybdev hid inupt us CPU: 0 EIP: 0010:[<d08f5d2a>] Not tainted EFLAGS: 00010046 EIP is at hpsb_remove_host_R34144dc5 [ieee1394] 0x3a (2.4.18-14) eax: 00000000 ebx: c1396000 ecx: 00000246 edx: 00000000 esi: c1a82c20 edi: 00000000 ebp: c1aec000 esp: cf143e7c ds: 0018 es: 0018 ss: 0018 Process modprobe (pid: 304, stackpage=cf143000 Stack: c1396000 c13974ec 00000000 d0889ff8 c1396000 c13974ec c13974ec 00000000 Computer locks up at this point...... I have 6 of these laptops and the same thing happens on all of them. Expected Results: Kudzu should have run normally and continued without complaining. This problem was not present with redhat 7.3 Additional info:
Created attachment 88697 [details] Here's the dmesg file from the laptop in question. This dmesg file has the whole error in it. It'll probably be more uesful.
Created attachment 88698 [details] Here's the dmesg file from the laptop in question. This dmesg file has the whole error in it. It'll probably be more uesful. (last attempt at uploading it was no good, so I'm trying again.)
Attachments aren't working right. Is bugzilla broken or something?
Created attachment 88718 [details] output of dmesg
The same thing happens with model PCG-GRX650
same on Sony Vaio PCG-NV105 Steps to reproduce (and have a shell or something to file this report): 1) in grub menu edit the kernel line and append init 1 eg. kernel /boot/vmlinz-2.4.18-19.8.0 ro root=LABEL=/ hdc=ide-scsi init 1 2) in shell start kudzu eg. sh-2.05b# kudzu Ooops: 0002 ohci1934 iee1394 ide-scsi scsi_mod ide-cd cdrom loop ext3 jdb lvm-mod CPU: 0 EIP: 0010:[<d08a3d2a>] Not taintet EFLAGS: 00010046 EIP is at hpsb_remove_host_R34144dc5 [iee1394] 0x3a (2.4.18-19.8.0) eax: 00000000 ebx: cfeac000 ecx: 00000246 edx: 00000000 esi: c1889d40 edi: 00000000 ebp: c1aec800 esp: cf1a3e7c ds: 0018 es: 0018 ss: 0018 Process modprobe (pid: ... stackpage cf1a3000) Stack: .... and the rest is more or less the same similar trace same Code in bottom line ---> the system is up to date (with up2date) changed in /etc/sysconfig/kudzu : SAFE=yes I'm trying two things next taking kudzu out of the boot-process and see if it works getting a vanilla-2.4.20 kernel and see if the problem remains. ... I'll be back ;)
initial workaround: boot with an appended: init 1 chkconfig --list kudzu chkconfig --level 2345 kudzu off reboot afterwards the system goes up fine. Next step will be to replace kernel with vanilla 2.4.20 (btw. I don't like your policy Redhat to ship a kernel, where the kernel sources do not match... most of the time I'm not able to recompile your kernel and have to pick a vanilla).
fyi: kudzu does not crash on vanilla 2.4.20 anymore. (but this might be my custom kernel). Moritz
Installed Phoebe 8.0.92 and 8.0.93 both run out of the box without this bug
It was a problem with the firewire driver on some systems. Kudzu happeend to be the apparent victim because it loaded the driver.
