Hi,
I made some tests overnight replacing 2.0.36 with 2.2.1 on our LAN server and encountered the following problems: (distribution is SuSE 6.0, gcc 2.7.2.3, used .config at http://www.lrz.de/~huettel/config.txt )
1) in <5min uptime, 2 kernel oopses, problems seem to be in quota code:
Unable to handle kernel NULL pointer dereference at virtual address 00000030 current->tss.cr3 = 01fb4000, %cr3 = 01fb4000 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[write_dquot+18/216] EFLAGS: 00010286 eax: c3cd0004 ebx: c2661bc0 ecx: 00000000 edx: 00000001 esi: c2661b60 edi: 0804ffff ebp: bfff0000 esp: c2035f6c ds: 0018 es: 0018 ss: 0018 Process sync (pid: 928, process nr: 71, stackpage=c2035000) Stack: 0804ffff bfff0000 c3caebc0 c3cd7e6c c0137456 c2661bc0 00000000 00000001 08048650 bffff568 c0127ebe 00000000 ffffffff 00000000 00000000 00000000 00000000 c2034000 c0127eef 00000000 c2034000 c0108c00 bffff584 0804aae8 Call Trace: [sync_dquots+82/116] [fsync_dev+34/48] [sys_sync+35/56] [system_call+52/56] Code: 8b 74 91 2c f6 43 2c 01 74 09 53 e8 02 ff ff ff 83 c4 04 80

2) during the first test the machine hung completely within minutes, last thing I saw in the syslog was
Feb 4 00:29:51 ntserver kernel: Unexpected interrupt 0
3) Oh yes, the command "sync" segfaulted (!) ...
4) the program diald I am using for dynamically accessing the internet produces a warning
Feb 4 00:27:56 ntserver kernel: diald uses obsolete (PF_INET,SOCK_PACKET)
(is this something I should take seriously?)
5) and I could not compile ksmoops (I guess this is rather a distribution-related problem):
(...) gcc -Dlinux -Wall -Wno-conversion -Waggregate-return -Wstrict-prototypes -Wmissing-prototypes -DDEF_OBJECTS=\"/lib/modules/*r/\" -DDEF_KSYMS=\"/proc/ksyms\" -DDEF_LSMOD=\"/proc/modules\" -DDEF_MAP=\"/usr/src/linux/System.map\" -DDEF_CODE_BYTES=1 -c oops.c -o oops.o In file included from oops.c:38: /usr/include/bfd.h:52: ansidecl.h: No such file or directory make: *** [oops.o] Error 1
I hope this helps removing some bugs... other question is, does anybody know how 2.2-proof SuSE 6.0 really is? (they claim to be...)
