Description of problem:
Tecra 8100 PIII850 w/ 512MB RAM, 20GB. Configured to dual boot with WinXP,
Suddenly (after reboot) started getting black and white grub splash menu
instead of the Red
Hat color image, then on boot, after loading the IDE drivers:
hda: IBM-DJSA-220, ATA DISK drive
blk: queue c03c9f40, I/O limit 4095Mb (mask 0xffffffff)
hdc: TOSHIBA DVD-ROM SD-C2402, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
Unable to handle kernel NULL pointer dereference at virtual address 00000071
*pde = 00000000
EIP: 0060:[c0118be9] Not tainted
EIP is at schedule [kernel] 0x119 (2.4.20-2.54)
Process swapper (pid: 1, stackpage=c23a5000)
<0>Kernel panic: Attempted to kill init!
That's all she wrote.
I did manage to get it to boot a few times, but only when the color grub splash
up. Kernel 2.4.18-14 (stock RedHat 8.0) panics with the same "Attempted to
message; both installs share the /boot mountpoint.
CTRL+ALT+SYSRQ works BTW.
Booting from the Phoebe 8.0.93 CD (2.4.20-2.21BOOT) panics:
<0>Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing
<0>Kernel panic: Attempted to kill the idle task!
In idle task - not syncing
Booting Red Hat 8.0 from boot.img:
RAMDISK: Compressed image found at block 0
invalid compressed format (err=1)<6>Freeing initrd memory: 506k freed
EXT2-fs: unable to read superblock
cramfs: wrong magic
FAT: unable to read boot sector
isofs_read_super: bread failed, dev=9:02, iso_blknum=16, block=32
Kernel panic: VFS: Unable to mount root fs on 09:02
I've even tried updating the BIOS to 2.50...no luck.
I can boot to a DOS boot floppy, but PartitionMagic 8.0 crashes; Ghost 2003
partitions, and even backs up to USB - but in DOS.
Based on bootup of another Toshiba laptop running Phoebe 8.0.93, it looks like
occurs when switching to *protected mode*.
Would make sense, because Partition Magic uses a protected mode runtime
termed a "DOS Extender".
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot from media (HDD,CD,floppy)
2. Select kernel
3. Kernel panics!
System was fine for months. Rebooted and then started getting a black and
white GRUB screen
intermittently for a couple minutes. After two subsequent successful boots,
GRUB is only in
black and white now.
Closing - old beta bug. If this happens on Red Hat 9 please re-open of course!
