All those files which have been created after resume is corrupted. I copied dmesg into a backup file and saved it. When i boot 2.4 and look into it , it is corrputed. After booting I connect to the internet through wvdial. So i have to load up usbcore,cdc_acm,uhci. i am connected to the net and searching on google. Now i do echo 4 > /proc/acpi/sleep . It suspends. Then i resume it from command line. So now wvdial looks as if connected but really isn't. So i close it and try running it again. It doesn't detect /dev/usb/acm/0. So i remove the modules and try inserting it (uhci) which gives me the error. Here is something which i could copy after resume. --> WvDial: Internet dialer version 1.53 --> Initializing modem. --> Sending: ATZ --> Sending: ATQ0 --> Re-Sending: ATZ --> Modem not responding. lsmod [root@mdk9 root]# lsmod Module Size Used by uhci_hcd 31752 0 cdc_acm 10784 3 usbcore 111828 4 uhci_hcd,cdc_acm [root@mdk9 root]# rmmod uhci_hcd [root@mdk9 root]# insmod /lib/modules/2.6.3-rc2/kernel/drivers/usb/host/uhci-hcd.ko ------------[cut here ]------------ kernel BUG at mm/slab.c:1269! invalid operand: 0000 [#1] CPU: 0 EIP: 0060:[] Not tainted EFLAGS: 00010202 EIP is at kmem_cache_create+0x509/0x670 eax: 00000031 ebx: c130277c ecx: c04a50e8 edx: c03cc3f8 esi: cf935fa7 edi: cf935fa7 ebp: cbdedf74 esp: cbdedf44 ds: 007b es: 007b ss: 0068 Process insmod (pid: 2234, threadinfo=cbdec000 task=cc1fa6a0) Stack: c036e980 cf935f99 00010c00 cbdedf64 c13026a4 c0000000 c1302668 fffffffc 00000020 00000000 fffffff4 cf938980 cbdedf9c cf91d0d4 cf935f99 00000044 00000080 00010c00 00000000 00000000 c03ceb70 c03ceb58 cbdedfbc c0137aeb Call Trace: [] uhci_hcd_init+0xd4/0x12e [uhci_hcd] [] sys_init_module+0xeb/0x1c0 [] syscall_call+0x7/0xb Code: 0f 0b f5 04 5a df 36 c0 8b 0b e9 71 ff ff ff 8b 47 34 c7 04 Segmentation fault --
