Red Hat Bugzilla – Bug 52778
Oops [Kernel 2.4.2 from bootdisk floppy crashes]
Last modified: 2007-04-18 12:36:41 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.3) Gecko/20010802 Description of problem: When booting with the 2.4.2 kernel from RedHat 7.1 on a Acer Pentium-100/265k L2 with 64MB RAM and a Cirrus Logic 5430 graphics card (1MB VRAM) the kernel crashes. Apparently it completely gets the wrong picture about available memory and later Oopses. A test bootup with kernel 2.4.3 worked fine. Also Redhat 6.2 works. However, I don't know how to create a bootdisk to get the CD installation going from scratch. So either an updated bootdisk with a kernel later tha 2.4.2 or some advice on how to create one would be appreciated, since the CD-ROM drive is not bootable. Here are some relevant lines from the bootup screen: Linux version 2.4.2-2BOOT (root@porky.devel.redhat.com) (gcc version 2.96 20000731 (RedHat Linux 7.1 2.96-79) #1 Sun Apr 8 18:24:33 EDT 2001 BIOS-provided physical RAM map: BIOS-e801: 000000000009f000 @ 0000000000000000 (usable) BIOS-e801: 0000000041505000 @ 0000000000010000 (usable) Warning only 896MB will be used.

Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: Probably system- and kernel-specific. Additional info: If more info is needed, such as the entire <dmesg> output let me know. An updated bootdisk on updates.redhat.com would be awesome!
Btw., adding the mem=64MB option to the boot: prompt did not make a difference.
Try mem=62M as usually the last megabyte or so is reserved by the bios.
Hi arjanv, thanks for the quick response. Your suggestion worked...I tried it with mem=63m and it booted fine for the first time. Out of interest, what would cause this? And how would you suggest going about creating a bootdisk for a given kernel (the BOOTDISK-HOWTO is not very clear in some parts...especially the compressed initrd stuff. A better document by RedHat would certainly help many people.) Thanks and take care...
bios issue not Linux
