Subject2.5.34 BUG at kernel/sched.c:944 (partitions code related?)
Hello!

Starting with yesterday I am seeing kernel BUG at sched.c:944
on 2.5.3[34], I've seen similar report for 2.5.31 in the list with no
responces, however 2.5.31 was working fine for me.

Stack trace for the BUG was entirely within idle task (default_idle,
rest_init, cpu_idle, ...)

It explodes immediatelly after printing:
hda: hda1 hda2 hda3 hda4 < hda5

Then panics trying to kill interrupt handler.

On 2.4 this partition layout looks like this:
hda: [PTBL] [7476/255/63] hda1 hda2 hda3 hda4 < hda5 hda6 >

Box itself is Dual Athlon MP 1700+. IDE only, 1G RAM, highmem enabled.

Other strange thing that caught my attention is this, if in 2.5.31 I had
this order or disk detection:
<4>hda: IC35L060AVER07-0, ATA DISK drive
<4>hdb: IC35L060AVER07-0, ATA DISK drive
<4>ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
<4>hda: host protected area => 1
<6>hda: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=119150/16/63
<4>hdb: host protected area => 1
<6>hdb: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=119150/16/63
<6> hda: hda1 hda2 hda3 hda4 < hda5 hda6 >
<6> hdb: hdb1

Now it does it in reverse like this:
hdb: host protected area => 1
hdb: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=119150/16/63
hdb: hdb1
hda: host protected area => 1
hda: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=119150/16/63
hda: hda1 hda2 hda3 hda4 < hda5PANIC

Is anybody interested in more information/whatever?

Bye,
Oleg
