[parisc-linux] "BUG: soft lockup detected on CPU#0" on recent 64bit k-2.6.16 (up or smp)

[Joel Soete]

Hello pa*,

Just to report some "BUG: soft lockup detected on CPU#0":
on b2k testing k-2.6.16-pa4 64bit up:
BUG: soft lockup detected on CPU#0!

This kind of hung re-occured on this n4k (64bit smp kernel 2.6.16-pa8);

I just grab the piminfo but useless:
[...]
Parse IAOQ =3D 0x000000ffff80ff3c for CPU[1]

Func: _end, Off: 0xffef1f1244, Addr: 0xffff80ff3c
[...]

Parse IAOQ =3D 0x00000000000006c4 for CPU[3]

[...]

Sorry,
    Joel

PS: I just start the same test but without CONFIG_DETECT_SOFTLOCKUP :<?

well never the less system still hanging after only:
top - 09:04:58 up 1 day, 16:26,  3 users,  load average: 2.40, 2.26, 2.20

training the same test (kernel build in loop)
(just this time without "BUG: soft lockup detected on CPU#0!" msg?)

Thanks,
	Joel

mmm, seems to help 64bit up kernel runing for a bit more then 3 days on b2k (building in loop kernel)

OTOH not for smp neither on 32bit nor 64bit:
	* 32bit smp 2.6.17-rc1-pa2 hang after some 2 days of run (loop kernel build) on a d380 with msg:

	* 64bit smp still hang silently after a bit more then 2 days of same build loop ;-(
	  (even with DETECT_SOFTLOCKUP = y?)
